Waste of money, in my opinion.
I had Revolutions in some CXP33s, and I thought they were too flexy, so I pulled the wheels apart after only 3 weeks and rebuilt them with non-butted DT Competitions (2mm) -- much better.
Champions weigh about 240g for 32 spokes (292mm), and the Revolutions are about 152g. So, while that's not a lot of weight coming off an 8 or 9kg bike, that's a fair chunk of mass coming off 32 spokes (~36%), and I reckon the big penality is a floppy wheel.
When the guy at the shop handed me the bundle of Revolutions, I couldn't believe how floppy they were.
If you want the shock absorption of butted spokes (I also don't think that's worth it), maybe go for a 'subtle' butt, like 2mm/1.8mm/2mm. Such spokes are about 40g to 45g lighter for 32 spokes.
I also reckon the DT1.1s are flexy. I couldn't think of a more flexy combination. I had some 1.1s but traded them for some 1.2s. The 1.2s also look better
