If he hits it hard great, but don't wait for it. So then I realized I was getting these cold water takes and started swinging at everything. Bad idea, let me tell you why. Anyway, the way he can take in this well O2 water without wearing himself out is to lie in front and behind obstructions like rocks and logs - also providing security. If it happens to be a steelhead and he has the fly well, great you are in the money but this is generally not the case.
Lets paint a scenario.
Lets say Leroy steelhead is lying behind that prominent rock and our fly swims by. Lets say it hits the rock, and we jerk. We just took the fly away from the fish, and possibly spooked him too. OK, lets say he followed out from behind that rock and just plucked the fly or maybe hasn't really turned down on it yet. We missed the fish, and definitely spooked him away.
