I have the 2" shorter bars on my 11 and 12 Pros and like them alot. Well, I bought a 13 and figured that I'd ride it with the stock bars just to compare for a while. I really miss the easier control and the other thing that was very noticeable was the fact that the stock grips are so slippery as compared the the RSI. Going back to the stock setup reminded me why I love the RSI bars so much, can't wait to get them on the 13.
