I just gotta put in my 2 cents on this. There is not a single lake that I fish that doesn't have some small wind current going 95% of the time. Keeping a deadsticked bait in the zone for 30 minutes isn't possible then. It does allow you to drift a bait over a target though. So while I have no doubt deadsticking a big trout bait will catch fish, the idea that you can consistently deadstick for 20-30 minutes doesn't make sense to me. So my take is that there is a teeny bit of exageration going on here. Maybe a couple of times a year you might hit perfectly dead calm conditions (and often even then theres a bit of current), and then you "might" have the opportunity to try the 20-30 minute deadstick, but I can't imagine this being consistent enough to spend a lot of time doing even if the conditions were right. Meanwhile slowing way down, and even deadsticking for brief periods will absolutely catch fish at times. Still my first approach is almost always a SLOW and steady retreive that says as Rob puts it "I'm a stupid lost hatchery trout please don't eat me".
