I have some hard rock maple shafts coming in for my 68"/53#@28" Jet Safari Premier Hill style ASL and was feeling a little anxious regarding what sort of point weight might be needed as in recent talks with Kevin Forrester I spec'ed them at 65# spine and they'll be tapered for 30"s long when they get here but I'm wanting to run heavy points on what's going to be a very heavy arrow.
Turns out that a 65# wood shaft spine is the AMO equivalent of a .400 spine deflection and I had plenty of those laying about so out came the bow, shafts and screw-in points in a variety of weights.
I started out with an "Almost Clean" side of my Block target and 300gr points that struck right of center (and I'm a righty)...

I shot them a couple times just to make sure and then switched too 200gr points and they struck a bit left....

The math was easy from there as I swapped the 200gr points out for 250gr points and bingo....

Howard was right about the stability of ASL's....this bow was defined about which way to go tuning wise and I also learned a few other things like the alignment value of shooting straight up while paying at least a little attention to string blur as part of the big picture which I guess explains why I see so many "White Strings" on Hill style bows.
The bad news is?...my shoulders are tore up as in shredded...I must've laid out upwards of 80-100 shots off this 53#er yesterday but the good new is I'll be healed up in a day or two and when I started out with this bow?....30 shots was a lot so my sessions are growing in shot count but my T-shirts seem to be getting a bit tighter in the chest and shoulder area's. LOL! ;)

Bill: You can't compare carbon to wood they react completely different.

Hate to say this but with my spine tester and Pauls at elite arrow 400 spine is 76# spine wood. Also harmonics of the two materials are different. So you did learn a lot but not sure it will relate well to woods . If you ordered woods that are 65 # spine I would be playing with 2114 2213 or 2018.

Bob: Thanks and I'm gathering that as I don't believe 30"/65# Maples are going to require 250grs worth of point weight off this bow cause if they do?...my arrow is going to wind up a touch heavier than what I'm shooting for.
Got any guesstimates on point weight?

Timbukto: Thanks for that as I'm well aware that "Charts VS Reality" are often two different things especially where dynamic variables are concerned but the good news is I factored in a little fudge room as I can go as short as 27 1/2"s long and/or just run lighter point weights as the maple shafts alone are tipping the scales at 540grs. (I asked for heavy)

Maple shafts may act a little stiffer than same spine carbons due to larger diameter.

Good job Jinkster. So many want to make weight changes 25 grains at a time. Change it a 100 grains so you immediately see results then sneak up on it.Nice bow,good lesson. >>>----. Ken

I burned on a 100gr and 160gr points to test at first but only took one volley to see that 160grs was far too much for these 30"/65# Shafts of Beauty so...

I immediately replaced the 160gr point with another 100gr point and got this...

you couldn't prove it by me as my 65# maples are a just a touch more limber than .500 spine Bemans...

Yes the above could be true on my spine tester a 500 beman is 63 pound spine

I don't think easton/ Berman use among standards for deflection.

Andy Man: I kind of cheated there as I noth lowered BH a touch and short stroked a touch to get that and they still flared a bit nock left prior to hitting the bales straight.
I'm chopping them down to 28 1/2" which will give me 28"s too BOP and should shoot swell with 100gr pys making a 600gr finished arrow.
This is the chart that was misleading too me where it looked like 6%3 woodies were equal too .400's...
