How important is it to have your bow professionally tuned? I got a new PSE Super G. I had it shooting well then I put on a Whisker Biscuit. The arrows are coming off the bow straight enough. But I know that doesn't mean much. The tuning kit I thought I ordered turned out to be an allen wrench set. :doh: Also I am looking at ordering the EZ center shot tuning tool (the one that attaches to the hex bolts on the front of the bow). Anyone ever use it?
