I got some carbon express,150 and 350 size.want to use them in my 45# frankenbow pulling 31". Both feather fletched.which one spine would work.using a flipper and plunger.

I would try the 150’s first.

Danny, even with your long draw, the 350 will likely be too stiff. You could soften them with a plunger of course, but I would think the 150's (.500) closer to your needs...depending on how heavy you are tipping. ;) Under 200 grains the 150 will be likely spot on. Give them a try since you already have them. Berger Buttons can make a world of difference.

150's go with

How do the CX ratings translate into the 400/500/600/700 system?

I had assumed that a 250 would be enormously stiff, but I have one from Wild Bill’s arrow bucket that bare-shafts pretty decently at about 29” long and low #50s for poundage....

I draw 29, have 2 widows,48@28, Pma and psa, 150's at 30" length tunes with 125 tips and total weight at 460 grains so 9 grains per lb. I prefer 250' with 175 tips (30 grain inserts) comes in at 610 grains Sure your brace height might be lower and you can mess with plunger but it will me "light" either way. Which is fine if that is what you want.

My info anyway

The 150's are basically a 600 spine, the 250's a 400 spine and the 350's a 300 spine.

Sizes: 75 (8.69gpi & .700 spine), 90 (9.7gpi & .600 spine), 150 (10.11gpi & .500 spine), 250 (10.91gpi & .400 spine), 350 (11.45gpi & .350

No bad, forgot the 500 spine... And I think you'd need a lot of weight on the tip of the 350's to get em close to spine from your bow..

I use 150s full length 145 gr point 47# at 32”draw. I also have used 500s with similar results. I paper tune and bare shaft. I get great results.
