Al,I think your approach has been crafted by a couple of things; One, you have honed and focused your skills to a point that you know what will and will not work and you have the ability to know when to stop fishing a non productive pattern, and 2, as you said you enjoy seeing the fish take the lure in the upper 1/3 of the water column. If your goal is to catch more fish and mainly aggressive fish (who wouldn't) this is definately the best approach. Sometimes you have to slow down to catch non aggressive fish though, and I know you can slow down as good or better than the next guy.
I guess it all depends on what you're after. I prefer to fish half way in between your speed and the average guy chunking jigs. With the jet boat, your options are greatly increased. Especially if you are familiar with a certain stretch of river. I end up running and gunning more than not, looking for a big fish. This approach allows me to fish out a hole a little longer than a guy with a canoe. And if you have a big blow up on a buzzbait, you can go back later and try again. I will admit that I'm primarily a jig and crankbait fisherman, but have expanded my horizons in the last few years, thanks to guys like you and others who are more than willing to give up your techniques.
As far as my favorite way to catch a big fish, topwater of course is number one. But to me a very close second is setting the hook on a jig fish that makes you feel like you are hung on a log, then in 2 seconds feeling a big slow head shake! Wow, I get crazy just thinking about it. Then, the fish stays down for 10 seconds and feeling the anticipation of how big it really is!! Then my only concern is deciding whether or not to get the net!
