finally decided on getting a 2008 rockhopper (providing they're not all gone)

one thing i'd like to upgrade in the short term would be to disc brakes, i'd probably go for the hayes set at £150 from Merlin, just checking these would fit the bill?

The hooper is disc ready, just confused by IS or Post mount as well as centre discs??

cheers
