My only experience is with a the 62 TSX. Results have been great and I've never caught a bullet when shooting for bone (which has been all of them). I'm a fan.
After saying that, I'm still hesitant to shoot for lungs only with the TSX. Almost all my hunting is heavily wooded mountain sides and if they run at all they are out of sight. I have no doubts it will work, but if I'm going to follow a blood trail I like it heavy on both sides... I need to send a few through lungs to get over it but I just haven't done it.
