its a bowtech...my friend had a hoyt and said he did the same thing. he took it to the same bow shop and they corrected his form and he said it fixed it.

Just seems its probably losing some energy having to straighten itself up first and then protracting forward to sling the arrow.

And by the way, its juiced up as hell, I told the shop to do whatever to make it 70lbs+. I know you think I'm crazy but I can pull it easily.
