RE: What trade off in let off?
8mm, you' re not the only one with an old bow. I have an old one that I think is from about 1976, judging from anything I can find. I do get a little laughed at in bow shops and such. Usually the employees hold back but the customers are a little more vocal. I have a 33% letoff, and I agree with it being quite difficult to hold, but I think I' m getting up to about that 20 second mark. I just hope I don' t get old.
I' ve been kind of planning to get a new bow also but I kind of like my 48" axle to axle length, except in the tree stand, or brush, the truck cab, ...I just can' t bring myself to spend $300-400 on a new bow just yet.
