Hi I've had my bow for a year now and want to get some heavier limbs now. The general advice is you'll need to change arrows, but to what degree is it necessary for a difference of one group or so?
Here is my current setup:
70" bow
SF Forged+ riser
SF Elite fibreglass/foam limbs (long) 30# @28", wound up to within 1 turn of max.
Draw 33" (to rest + 1")
On the fingers poundage is 41
From my reading of the charts that puts me at top end of T10 or bottom end of T11 (extrapolating)
My ACEs are 430 so are in T10 for recurve. The arrows are full shaft length with 120gn piles, just under 34" from nock to tip.
I was thinking of upgrading to 36 lb long limbs starting with the bolts fully wound out, so would estimate about 44-45 on the fingers which is top end of T11.
To me it does not seem to much of a jump in terms of arrow spine, but what effect would that difference have in the real world? I could trim 0.5" off them fairly safely, and also reduce the pile weight a bit as they are the ACE break-off points. These arrows cost me a lot more money than I wanted to spend at the time (ACCs were too short in stock length meaning not much margin) and I don't want to have to replace them just yet if necessary.
