There are absolutely no benefits at all with YOUR particular bike... Especially with the RS wheel where you will now have to run a 160 section rear tyre!

Tell you what, sell me the RS wheel, as it's of no use to you what so ever, and I've got a nice shiny painted 17x4.5 wheel with a nearly new D208GP you can have instead... It's better I take it off your hands just to be sure!
