Well, I have joined the Matthews ranks for the first time and acquired a Z7 extreme. Thought I would come to the "experts" \:\) and ask advice on setup. The only thing the bow has on it is a QAD rest. Here are the things I would love your input on what I should go with:

Rest - Stick with QAD?
Should I go with Focus Grip?
Stabilizer?
Sight? Considering IQ
Arrows?
Broadheads? Considering 100 grain Ramcats after positive experience with them last year.

Any other input/lessons learned are appreciated. Thanks!
