Mike is actually a great friend of mine. I go ove there often and have had over 1/2 dozen bows done by him in the last 4 years alone.
I won't post exact speed gains cause, I can tell you my two Chronys I have at home do not read as fast as Mike's Chrony but, they are faster and better yet; tuned to shoot way better.
Mike finds the best efficiency settings for the hybrid or dual cam to make it "zing".

He is a lil back logged right now but, give him a call.
