Cheers man, that's really helpful especially as you've also gone through a few different brake setups yourself.
Going over to Bonz wheels soon, hope to put an end to this. Don't really want TR rims, they're soo heavy
The Sport and SL rims are the same thing. Before the new range of SL rims was introduced, the only difference was the colour. Now, the only difference is that Sport rims have round holes and SL's have square holes (as far as front rims go obviously, the rear is quite different).
