My pro shop misinformed me of the stats on my setup. I was doing some tuning and measured the weight on my bow. It's 73, not 83. So I called Bowtech to find out if there were 80 lb limbs available, and the answer is no unless you have a Guardian. Not happy. So I put it through the chrono and got a disappointing 340 fps. That means that there is something wrong with the chrono at my pro shop. I'll let them know. Let me be the first to admit that I may have known that the chrono was off. Sorry for reporting the data out of a bad chrono. I'm not mad, I just need to find an other way to be the fastest.
