Got the bike back today with the Ohlins cartridges and the WO575's installed and I am extremely pleased. I only got a chance to put about 30-40 miles on the new set-up, but I can say the ride quality is greatly improved. The small, sharp bumps that used to jar the bars, floorboards and my butt are well controlled now. I have a compliant but controlled ride on the highway. I am heading out of town for work for the next 7 days, so it will be awhile before I can report on how it handles the twisties, but I do expect big improvements over stock.
Just for comparison, I also have a Goldwing with Progressive Monotubes installed. I also did All Balls steering head bearings and a stiffened triple tree at the same time on the Wing. The Monotubes also gave me a big inprovement in ride quality. The only drawback with the progressives were a one-size-fits-all spring selection. The Ohlins came with springs matched to my weight & riding style. I guess the big question is: Are the $980 Ohlins better than the $260 Progressives? My answer is yes.....are they $700 better?......subjective, to be sure, but I am happy with the result.
