I am starting to follow the same route with my tackle. I've sold most of my 6-7 wt stuff and now am happy with 8' 4wt and 7' 3wt rods. I too have downsized my reels to suit.
Guess it started with the 8' Hardy Ultralight rod that came in a deal about 6 weeks ago. Matched with a Rio Gold line it casts very well and easy to put out 20 yds if need be.
Suprised me how simple it is to fish with. Close range it's a cinch, just a flick and it's there. Recent first outing was to a local 'pond' a test run really, caught 4 rainbows around 2-3lb mark, the rod was faultless. So light and flickable, made me smile. Have since added a Featherweight 7' 3wt. Not been out with that one yet but hopefully tomoz.
For me the 'lightweights' are a breath of fresh air. It's been a long time since a rod/set up made me smile. They definately have the wow factor for me. Not bothered about wind, as you say it's simply a matter of adapting. Although I fish mainly rivers I have no qualms about using the 8' for the odd occasions on a stillwater.
Horses for courses but hey the lightweight approach really is fun-I'm sticking with it
