sorry didn't see that last post. When i spoke with the rep from JP we talked about what division i was planning on playing in, he suggested a 20 for irons and an 18 tactical optics, because i am planning on shooting in tactical optics i went 18. The one thing i'm worried about is weight, but i think i will just work out some more to overcome that. From some of the other forums i read it appears all of the top guys use a 20 but i'm 5'6" 130lbs, so i just cant see my self holding one of those up to well at this point. My friend recently went down from an 18 to a 16 because he didn't like dragging so much weight around. I figure if i just get into better shape i should have no problem handling the rifle.
