Well, it's now fixed. Turns out it was just shop incompetence. Luckily, I had an option. Had to drive 2 hours one way to exercise that option, but it was worth it. After fixing most of the problems myself, I took it to a real pro to get it the rest of the way. He helped me tune it, re-time the cams, and help me choose the proper arrow. After buying 6-7 dozen arrows of different sizes, weights, spines, etc., all in an effort to find what worked best (without really understanding the selection process), I finally settled on the arrow I'm going to shoot. And on the upside, it turned out to be the lightest, fastest, arrow I'd tried. My PSE now shoots like a dream, and while at the store, I tried about 11 different bows while he was working on mine, and I'm convinced the PSE is the best bow on the market currently, at least for me. It just feels right for me. Dude didn't even charge me! Thank God for Richard Albritton at Simmons' Sporting Goods! He's as good as I know...I just wish I lived closer.
