About to mount my third set of Roadsmart III's after years of PR2, PR3, and PR4's. I've been getting maybe 500-1000 miles more on the rear RS compared to the PR.(5500-6000mi vs 5000-5500mi) I usually change front and rear together, giving away some miles on the front. Milage aside, the greatest improvements I notice are a much smoother turn-in requiring less pressure on the bars, less loss of contour as the miles pile up, and much reduced cupping of the front. The front especially does not seem to flatten on the sides like the PR's would, which may be responsible for the more stable handling with increasing wear. Can't speak to the wet handling issue. For reference, I ride a K1300GT, trail brake a lot, and enjoy dipping into the throttle liberally. I'm not a little guy either...250 easy ATGATT. I see little reason to try anything else. Most of my sportbike riding buddies have switched as well, even HP4 and Panigale riders.
