Ariel, I can see if you're leading the fly with the rod (Czech style) you can provide a quick jerk for a hook set and ensure you don't lose your catch, but (and this is really something I have seen play out often this past season) with the fly being intercepted downstream (or anywhere from perpendicular to the angler and downstream) the most effective hook set is a confident lift of the rod. I've lost a lot of fish by giving a quick dry-fly hook set when I felt or saw the take, but I have missed fewer fish lately when I can keep my spurs from jangling and just lift into the take. I'll be the last to step in a conversation about the differences in hydrodynamics, aerodynamics or centrifugal forces (like the ones at play with a fly on a leader), but I have lost a lot of fish with the fly downstream and what feels like the fly being pulled out of the fishes mouth. I like the comment that the fish plays a large part in the hook up, no matter the angler's technique. For myself using a steady and confident lift to set the hook seems to have doubled my catch rate. That's worked for me, but we all have worked out our own methods and if it works, there's nothing to be said other than please share what works for you and say it often. I seem to require being told a thing a number of times.
