Never held one so I really can't say much about that one but I have fooled around with bows and got them to do different things.

It could be the way the strings and cables are setup if they have more than one string. Increasing and shortening them can get you some comfort for speed and some speed for comfort. I really don't care for using "the one that felt the best" approach because the bow might have strings and cables on it but no where near where they could be.

It has to do with where the cycle breaks in the draw. Some peak early and break late and some peak early and break early... Those draw force curve box's tell a tale. The more the box is filled the harder the draw because your storing more energy put there by you. Your still pulling the same weight but not for as long or longer which ever the case maybe.

That's the way I've gone at it and it seems to work for me. Hows the speed of the bow? You might find it's a little faster than some smoother ones.

It could also be a mechanical problem. I just had a bad cam and now that I think of it the metal industry has been squeaking out it's products the past few years and it wouldn't surprise me if the quality has suffered. Copper pipes made in a similar time, the late seventies suffer the same fate, to much steel and not enough copper caused them to rust. Copper and rust doesn't happen. Saw some cast iron pipes suffer a similar fate. Buyer beware these days. Wait a few years and see what happens in the building industry. By law they were force to change things like the glue that holds them together. The new stuff is junk, nothing more than latex caulk. A lot more than you wanted to read I suppose
