I have a set of Avon grips though not those. I like them a lot better that the stock, though there is a very slight side to side looseness in the throttle side that wasn't there before.
It's not really noticeable unless your looking for it.
I am using the Avon Grips. They are around ½" longer and have a larger diameter than the stock grips. They are very comfortable. The slight side to side play is easily fixed with a very thin "O" Ring between the grip and control mount.
