Folks, don't be bashful about offering up your ideas on this I won't hold anybody accountable :)
I'm building a proven ASL design. Sixty eight inches NTN. I have an accurate model that predicts draw weight changes with stack variations, but now I'm going to shorten the riser from 18" to 14 1/2 inches. So, that will be an increase of 1 3/4" to each limb.
What might be the draw weight change expected?

I normally don't give out my knowledge on glass bows. But since it's you, I will.
5#

OK! So far it's established for certain that it won't be five pounds :biglaugh:
Seriously, Roy, thanks. I was thinking about the same but want to hear from anyone who has an idea on It.

You're basically increasing the working limb length by 1.75" on each limb. Assuming, increasing a limb by 1" decreases weight by 5 lbs, I'd GUESS you'd lose 8.75 lbs. (Notice the emphasis on "guess")

John, thanks for the info. It seems like a lot of weight but using that number would allow me to stay in the weight range needed.
Bow is for a young guy who is plenty strong but I don't want to accidentally over-bow him since it will be his first bow as he begins in archery.

The example I am giving is not the same asl bow design. The example is a 60" d/r design Kenny M form - same stack of .300 with 18" riser is 43# and with 16.5" riser is 37#.
