Hi, I am also considering similar equipment changes coming up. My view at this point is to try and maintain an overall consistency in club speed at some expense in performance. The R11's look very attractive and I have read lots of good things, but I am not crazy about the difference in club speed compared to what I have (similar to yours). And, like you, I have matching speeds for my driver and 3 wood.
I decided to buy the 1st available ATV wedge (56) after trying it on a free rental weekend. I was happy with it's behavior (very steady with a little less backspin than the Cleveland) and... it matches my other club speeds. I expect to pick up the 60 deg ATV also on my next level up. As for the 64... well, the strong backspin for better scrambling on the Cleveland might trump the slightly faster meter speed: the distances involved are more forgiving for missed dings. BUT I will strongly consider the ATV 64 in order to have equal club speed across the board, which I believe helps with my timing on the long distance clubs (200+ yds) where getting close to the ding is crucial. BTW I would recommend sacrificing your hybrid for an extra wedge to boost your approach game.
I am very happy with the SDLR and will compare with Big Bertha driver coming up before buying. I will likely upgrade to the BB 3 wood as well, we'll see. By the time I am considering the 97 level Nike iron set I hope to be comfortable enough with my rhythm that the performance advantage will trump a .5 change in meter speed. Again, we'll see.
Best of luck in your choices and enjoy!

Edit: another consideration when looking at equipment at this level is a good matching golf ball. I am not familiar with what you are using, but an upgrade to your ball might be needed to enjoy the advantages/performance of new clubs you are considering.
