Number one, what's your new bow rated at compared to the older one? They may be fairly close. Another thing is that these bows are rated by IBO, that means a light arrow. You are shooting closer to AMO. When you look at bow specs they are all over the place, from 290's to mid 300's. When alot of these bows are set up for AMO specs they tend to be much closer. Most speed bows from what I have been told don't shoot much over 250 something in an AMO configuration. I'm sure the bowtech dually's will do better than this however, but I bet not much.

Might be something up with your bow however, worth having it looked at I guess.

What bow did you have, and what bow do are you shooting now?
