For winter fish, it's probably not a big deal, because the fish may be less likely to follow a fly from their lie all the way to the end of the swing. But in the summer, when the fish move farther and are generally more agressive, I think fishing the strip gives you a lot of bonus grabs. The guy who got me started flyfishing for steelhead insisted that you should, whenever possible, 1) wade deep enough for the fish to be comfortable following your fly to the hangdown, 2) patiently let the fly hang on the hangdown for a few seconds, and 3) do two steady, deliberate strips with a pause between them and another pause after them before continuing to the next cast. He said you should do this as routinely as you do any other part of your cast. It takes a lot of focus and discipline at first until it becomes a habit. I've caught a lot of fish that way. In fact, on some trips, it has accounted for a large percentage, like 5 or 6 out of 15 fish hooked. If the fishing is good, it almost always gets one at some point during the trip, and I can think of a couple tougher days where I got my only grab on the strip. In short, it works. I never really pay any attention after the second strip, but I've had plenty of fish grab anyway on the fifth or sixth strip. One time I was fishing a scandi head and had one grab it on the eleventh strip! So, I understand the desire to fish longer lines that don't require stripping. I like them too. But I also can't deny that if I'm not stripping, I'm missing some opportunities in the summer. That fact probably bothers some people more than others.
