I'm about to replace the worn out brake pads on my Avid Shorty 6 w/ Shimano XTR pads which fit perfectly. However these are very squeaky and noisy. So, I've been advised to replace them instead with:

Ritchey V-Brake Pads

Has anybody fit these w/ no problems in the Avid Shorty 6 brakes? and
Do they come also w/ the little clip that secures them in place just like the Shimano XTRs?

Thanks,
