I had a similar experience with the Trophy Taker. I tried it on 2 bows. One bow I could not get tuned correctly. This was with Nitro Traditional tapered arrows. Arrows flew tail right no matter where I moved the rest or nocking point. These arrows are pretty stiff, and not specifically spined for one range of bow weight.

The second bow worked better, but I was getting some fletch contact. Because I was using feathers, it didn' t seem to affect the grouping too much though. I did build up a arrow holder of sorts as per the instructions on the video tape. It worked well. I did not have any problem with the arrow not being picked up properly, even when canting the bow at about a 45 degree angle.

I also tried the Muzzy on yet another bow, and would have to say that functionally, the rest was better and more reliable than the Trophy Taker. (no shelf or contact problems)

I did not see a significant improvement in grouping or broadhead accuracy with either of these drop aways. Just my experience.
