Guys, I took my bow to the shop and had my draw length checked. My bow said 29" on it but it had been changed to 27". So now I know my draw length is 27". I also had a string loop installed. I did not have time to shoot before I left the shop and now I think my nocks are being bound too much by the knots on the loop. Anyone have a suggestion on a fix for this? Also I had the Trophy Ridge Drop Zone installed (served into down cable). My groups at home this evening were pure unadulterated BS! I couldn't even hit my 3d target 3 out of 6 shots. I saw a trend on their flight and adjusted sight accordingly. This helped (could hit target), but arrows are still not grouping at all. Some hit high, some low, some right or left. What does this sound like and where should I start to work this out? Sorry for the long post, but I need help. Please....

Thanks, LT
