I'm using a 45# longbow.
500 spined carbons, and bear razor heads.
I think they are right around 400grs.
I think my foc is decent, I get good flight anyway.
Is there one method better than another to up the weight?
Thanks

Brass arrow insert, or heavier broad head. 450 grains of arrow would make a great match with your bow.

Not really, and if it an’it broke why try and fix it. BUT to somewhat answer you question. Heavier BH would work but may need more arrow length plus BH’s are expensive. Brass inserts work as well but agian may need more arrow length. No matter you will have to retune and dollar to donuts you will spend some bucks.

Leave it. You do not have to have the all mighty 10gpi. Brass inserts cost money and are not as effective as tip weight. Your good arrow flight is whats important.

Lots of "weighs" :) to add weight, several have been mentioned. That being said, if your after whitetail I would stick with what you have. It's just fine and dandy. Like Cameron said, great arrow flight is key to this entire game. Nothing good can happen thereafter if the arrow isn't tuned to start with.

Maybe find a different brand shaft with more grain per inch weight,in the same spine. But that wouldn't be much of a difference.

50 grain brass inserts give you a modest gain in arrow weight and foc. I tried 100's once, too much up front for my taste.

Not unless you want to retune your bow. Not sure why you want to add more weight if you’re tuned with good arrow flight. You’re still getting 9 gpp . Will still stick in the ground on the off side of the deer. Also should have excellent trajectory at that weight.

How much weight do you want to add?
As you can see there are bunch of ways to do it, but depending on desired outcome some may be impractical or overkill.

What flavor of carbon GT tread classics are heavier than normal carbon. Might be an option. But you never said what flavor you're shooting. JF

I am another who agrees with Rooty on this one….
Depending JUST MAYBE on how well you are tuned in the first place. I don’t know the OP here from Adam’s Off Ox, so not making any assumptions about anybody, but I sure have seen an awful lot of people shooting arrows that are much too stiff in the first place. I was one of them, for about 20 years, so no offense intended!
But FWIW, I shoot 28” 500s at poundage in the #52-#55 range, with 200 gr up front. So JMO…
If you are not shooting those full length, I would think you have to be way overspined anyway, and unless you have extraordinarily long arms, you could always trim a little length.

There's lots of ways to do it, that work just fine.
Added point weight.
Added nock end weight
Added weight at both ends
Added weight over the full length of the shaft.
I would say, that the easiest way to accomplish added weight is with the weight tubes, but I recommend anchoring them once they are inserted. I anchor them with hot melt at the nock end, and cut them just short enough to accommodate a full & secure nock installation.
Just keep in mind: Any weight change of the arrow changes the load on the string, so it will definitely impact the dynamic spine of the arrow.
That impact may, or may not be noticeable, and need a tune change, but in my experience it usually does. Just depends on how much weight you add.

Shb, 2 or 3 pcs weedeater cord cut to fit from nock to insert inside the shaft will do it. If that's not heavy enough aquarium tubing (if you can find it..covid..) will make them real heavy. Neither affected spine that I could see.

What are you hunting? Buffalo, then yes you need a heavier arrow, deer your fine. Add some rope or some arrow weights.

I like to trim my arrows to the minimum length, 29.5” in my case, then add point weight until they tune right. I never liked the results I got when adding things inside the arrow.

There’s plenty of options but I would choose to stick with what you have. It’s funny on how we want to improve on everything I do the same but when I think back the first 10 years or so of shooting a stick bow I never even gave my arrows a second look as long as they flew good and were sharp away I went

We use weed eater cord. Buy a roll of it, cut to length, and insert into arrow.

Now hold on a minute, fellas….
Adding weight tubes may not affect the spine of the arrow, but any meaningful amount of weight added to said shaft will CERTAINLY affect the dynamic spine requirement of the bow. A well-tuned bow is a balanced system with a lot of George’s gozintas, and you can’t just change ONE and end up Right unless you were Wrong to begin with….
Heavy up the tip and you will need a stiffer/shorter shaft; heavy up the entire arrow and you will need a weaker spine.
I think the OP here is either overspined or (unless he’s a particularly long-armed feller) he likely has room to bump up the tip weight and shorten his shafts as proves necessary.
Just depends how long an arrow he prefers.
If flight is good, he can stand pat…. Or he can go to town on tip weight, tubes, etc. and get whatever he wants out of the deal.
Truth is, there’s a righteous merry boatload of solutions, if you’re of a mind to come out at a specific GPP or FOC or length or All Of The Above. Or you can start with too long an arrow and too much point weight and keep trimming until you hit Right.
As just one example of a simpler approach.

I bought some weight tubes many years ago. Field points flew well with or without, but switching to broadheads the weight tubes definitely changed the dynamic spine, stiffening those arrows.
Another thing I didn't care for, the first couple inches broke apart inside the arrow shaft after a lot of rough stumpshooting. Also had to glue nocks in to keep the tubes from popping nocks out on a hard impact.

I have some extra shafts, I might try filling with expanding foam.

The foam works, but don't get the cheap stuff.
Get the good stuff, it will expand more evenly, thus distributing the weight more evenly.
If you don't get it right, it's a booger to clean up, clean out, and start over. :D

I gotta go with Rooty on this one. You're trying to get over 10gpp and I complain because without going to carbons which I hate I can't get under 10 gpp since I dropped bow weight. My long draw prevents it in wood or aluminum.

Insert braided nylon or poly rope for 2/3rds behind the insert. Need to pull insert and insert rope with a thread through center of insert. Put dab of glue to back of insert and shove in.Pull thread to lodge rope into glue on back of insert. Let dry with nock end down to prevent glue in the threads and end of thin thread secured with a bit of tape so rope cannot slide to nock end. You can do 1/3 2/3 or full length. Can add 100 grain to a 28" shaft, will only affect spine through mass (99.5% of shooters won't notice). Weight tubes tend to rattle an if they have not full contact on the shaft's intetior wall, they will affect dynamic behavior. Very easy to observe with selfbows or bows not being cut padt center.
