yeah fair do's you can get some very nice and still pretty expensive smaller wheels and there are alot of 'halford special' wheels hanging around that look really ******, not saying mine are great as there are many id prefer to have, but it really does depend on the look you wanna go for!!! when i got a flat and had to change back to my 15" hubs i almost killed myself on the first corner i went round because of the speed i was used to....
Mine has never bounced around, always been obscene amounts of grip, i have also got upper and lower strut braces on, i guess that makes a pretty big difference...
