Jeff knows a heckuva lot more about ACC' s than I do, and maybe he' ll ring in here in a spell.

I' ve been over to Jackson' s and nosed around on the arrow selection chart. Looks to me like another 5 pounds of draw weight would put you in 3-71 with a 125 gn head. That' s awful close.

I haven' t had enough caffiene this morning to fully engage the brain, but I' ll try to go through this without rambling too bad.

I' m shooting a bow that' s 10 pounds less than you' re looking at, with what amounts to a hard round wheel or very mild cam BUT 3" longer arrow at 33 1/2" draw and fingers release. Fingers release jumps spine up by 5-7 pounds in the charts. Round wheel vs hard cam drops 10 pounds on the charts. Add in 3" of arrow length adds 15 pounds on the charts. I' ve been shooting mostly 125' s on this 3-60, but out of curiosity I mounted a 160 gn Magnus 2-blade (125 gn head on a 35 gn adaptor) on that arrow. It flew like a dart! 25 grains = 3 pounds of spine.

Starting at 60 pounds, subtract 10 pounds for round wheel, add 7 pounds for fingers vs release, add 15 pounds for arrow length and I' d need the same spine arrow as someone shooting a 30" arrow with release from a 72 pound hard cam bow. Add in the 3 pounds for the 160 gn head and that would bump me up to 75 pounds. But, plugging my numbers straight into the chart, 75 pounds puts me in 3-71!

So, just like you, it' s showing me on on the upper edge with 3-60. I' m doing very well with a 3-60, so I think you can do the same. Problem is, when it' s that close it' s hard to make a decision just based strictly on the charts. Trial and error is the only way to really decide but, in the case of ACC' s, error can be expensive.

Hopefully the dealer will have a couple of odd out ACC' s in both sizes and you can shoot them side by side while trying out the bows.
