Perfect advice from the guys above about getting it submerged. You don't want that fast water swinging it to the top. In that fast of water I don't try to retrieve it. In fact I'll do the opposite, and let the current take out more line once in awhile (I've been all the way to the backing when I've hooked-up, 90'). When you do bring it in check to make sure the tail isn't fouled around the point, or it's got stuff on it. My catch rate went way up when I started checking/shapening the hooks on my buggers.
