I made a post awhile back about how you got to fiddle a little even w/ Slicks to get the alignment right. I had just got done using the loaner ASD Dnk has floating around the xbow forum members and what I neglected to tell ya'll is I launched one of my coveted wrapped hunting arrows and a brand new Slick into the ozone at 30 yds due to run out. Well, needless to say that really whizzed me off, so I got ahold of mybuddies defunct arrow straightener for alums and after I fixed the dial indicator, I moved it so I could run b-heads under it. My, My, did I get a lesson here! I had as much as .012" run out in some I thought were perfect. I got all 8 of my hunting arrows under .004 by fooling w/ washers and retightening them. Got some pics if anybody wants to play w/ their arrow straigtener, I had to redrill this one to get the ind. where it is.
