Ok, let me start by saying I know very little about bow tuning. But, that's why I'm here. My bow (2003 Hoyt Protec) WAS shooting great, but I was getting some fletching contact with my Trophy Taker Shakey Hunter. I had great groups out to 50 yards and arrow flight was "dart-like". Yet, I had some streaking on my blazers indicating the fletching contact. So started reading. Read two threads about exactly where the release string on the TT should be tied into a Hoyt's cables as well as timing the rest to stand up in the last 1 to 1.5" of draw. I read that the release string should be tied into the cables 6 inches below the arm of the rest with Hoyt bows and mine was tied into my cable at only one inch under the arm of the rest. When I drew, the rest would stand upright about 3 inches before full draw. So I went to work, and retied and served the string 6 inches below the arm to time at one inch before full draw. Shot my bow and immediately noticed porpoising arrows. Then read about walk back tuning and center shot. Looked awesome! I started through that process as well. But I am having difficulty getting arrows to consistently group directly under a 20 yard bullseye as I walk back. Seems they're left one time, so I move my rest slightly right...then I have it perfect for a couple of groups. But then later groups end up right of the verticle line. Plus, my groups at 30, 40 and 50 have opened up as well. Used to shoot 2-3" groups at 30, and now am shooting 5-6" groups with "flyers" here and there way out the group. Still hitting a quarter at 20 yards quite regularly though, but can see the arrow still rolling as it makes its way to the target. Took my bow to the local archery shop, they "eyeballed" it and said "everything looks good"...must be you. It probably is, but I'm not shooting nearly as well as was. I know, should have left good enough alone...but just wanted it "right". Any thought on what I should do now?
