also think that speed makes having your distances correct less important cause it will drop less over the same distance but if you can't get it back and get it steady when you need to you should back it down

I now shoot at #61 (maxed).

If you are shooting it 30 times until fatigue at #70, and limbs usually go 40-50, 50-60, and 60-70,
I don't know why you should go all the way down to 40-50 limbs. Get a fast 50-60 bow and you
should be in business. My bow shoots flat out to about 24 yards.

I shot 70 then bumped down to 60+ and found much more comfort and no more shoulder problems. I also find that I can hold full draw for a much longer time in those too often cases where you need to draw in advance of the animal getting in shooting range or in the clear so you don't spook 'em with the draw.
