This might be the best concept in a thumb release so far. Picked one up last week and used at a TAC style shoot this weekend. I think it improved my accuracy.
Short video with Joel Turner and PJ Riley.
Haven't bought the FD5 yet but I will be. I currently am using the FD4 and it has been flawless at all of the TAC's and other Mountain shoots I've used it at. I think 6 different mountain 3D shoots now.
