i shoot a bowtech, and my tt actually didn't have to be as high as my bodoodle, but both had to be a little high (nocking points). make sure your cam is timed and your ata length is correct. besides that get center shot with paper and do some group tuning. if you're getting a nock left tear move your rest a little right. if you have to be a little high to make sure there is no fletching contact - so be it. i usually group better a little high anyway. for me it comes to a point where you really have to be an expert to get some of these drop aways to shoot paper perfectly. the trophy taker website has some great tips for tuning it though. someone recently said they shortend the rope and it worked better - but tie a knot while testing, don't cut it - i guess you knew that. hope that helped a little.
