RE: which arrow rest
Ain't this gonna be fun! I'm sure there are probably lots of opinions on this one but I'll give you mine too!
While I like the GKF series, I'd be inclined to go with the Trophy Ridge Drop Zone. You can pick up either the "Hunter" model or the plain "Drop Zone" model for under $100 and so far, I've been shooting great groups out of it. I would not, however, recommend spending the extra money on the guide series...
