It is such a matter of personal preference, that I probably shouldn't comment, but that has rarely stopped me, lol.
I have owned or shot most of the top end r/d longbows available. The TT Stickflinger is by far my favorite. It is possible that you get a few more fps with the absolutely fastest performing bows out there, but that would be about it. It is exceptionally smooth and quiet. Like with all bows, for the most part, it is the grip that makes a huge difference. I love the grip, and find it to make for very repeatable hand placement. If you were a lefty and lived around here, I would invite you to try one of mine. I know several people that have said that they are the best bow that they have ever shot after trying one, but I won't put their names down here. My greatest endorsement is that if a tornado came, and I could grab only one bow on my way to the storm shelter, it would be my Stickflinger, although I would certainly mourn my Silvertips.
