I have a 39#@28", 62" bow on the way. I draw 29". When I run the numbers through the 3 Rivers spine calculator I get a Dynamic Spine of 67. My Pinnacle 2 with 46.5# limbs has a Dynamic Spine of 55.
Can the ACS have that much more? Maybe the calculator is making an error.
I ask because I am trying to determine what arrows to get.
Do these ACS bows have that much more potential in them?
From my experience yes. Seems when you combine high performance limbs and the fact that the riser is cut past center, it requires a way stiffer spined arrow. My current setup is an ACS CX that is 54# at my 30 1/2" draw. I shoot Easton FMJ 300's with 150 grain point.
Big Sneaky,
Thanks, that must be a sceamer.

My A&H ACS takes a stiffer spine then my other bows of similar weight.I even built out my side plate,I believe A&H risers are cut 3/16" past center.
Yes, they do have that much more "potential". I can easily shoot CX 75/95's out of either my 51# or my 54# ACS. I also shoot MFX 340 out of either. What works best are the 400's Nanos or the MFX. I draw 28".
I typically front load 300gr. - 400gr. so stiffer is better in my case. Many other tuning adjustments influence what one can shoot, ABT (Always Be Tinkering) ;)

So is it that they are cut that much past center or the limb design that gives them more potential.
Kris, I like that "ABT".

Both, you will still be able to shoot a .600 spine At 30 inches with 175 grain point, if you go to .500 spine you will need lots of point weight and a 30 inch arrow, around 300 grains. Those calculators have everyone overspined! Shawns
1 piece or 3 piece ?
The 1 piece bows are cut 1/16" past center but with the 1/8" thick Velcro shelf material it brings it to +1/16" .
The 41# ACS that I had shot 500 spine 29.75" with 125 grain perfect and I have a 29" draw also. Good luck, I don't think I would try a 600 spine arrow having a 29" draw lenth.
It's a one piece.
Caught, thanks for the arrow info.
