Correct me if i' m wrong, but " logically" if you increase your draw weight, you will gain fps, thus flattening the trajectory a small amount. With out moving your sight any, this should cause the arrow to rise a small amount, not drop.

Becuase of my career as an Information Technology professional, I have to ask an obvious question here. And this is not to sound one bit demeaning.....

-Have you tested the draw weight after adjusting it (I' m sure you have) to make sure you were actually increasing the draw weight instead of decreasing it?

I' ve found that myself as well as a lot of my clients tend to miss some of the obvious stuff. Like i said though, i' m not trying to be demeaning or anything of that sort. Just trying to help out. This seems to be a tough one.

Good luck, Hope it works out for ya.
