Ok so I went with the ICE TECH 160mm for now. I will upgrade my front set to 180mm bit later and re-use the current 160mm front on my road set. Built the wheel set and it looks good.

Ok great so going to the 180 size is actually a good thing. What makes me worry is the fact that my SLX brakes now need to be spaced to accommodate the 180 size. Would the adding of spacers have a negative affect on the quality, stability of the brake system? If you had to take a rotor from the LBS (http://www.cwcycles.co.za/catalog/parts/disc-rotors) which would it be? right price, quality, size etc for my size. Maybe something like this for the spare road wheel set http://www.cwcycles.co.za/product/alligator-motion-disc-rotor And something like this for the MTB set http://www.cwcycles.co.za/product/shimano-xt-ice-tech-rt86-disc-rotors-6-bolt or would you also go cheap cheap for the MTB set?

Hi I bought myself new set of ZTR ARCH EX rims with Hope Pro 2 hubs and need to get Disc brake rotors. LBS suggested that I go from std 160 rotors to the bigger 180 rotors. I am 6.6 and weigh in at 113kg. I have my old set of wheels with std shimano 160 rotors which I am going to use as a road set with slicks. Going the 180 route I would have to space the brake set to accommodate the bigger rotors. Which in turn would null and void my road wheel set rotors. My question is is there really a big difference in breaking power between 160 and 180 rotors? And looking at the Hope Saw Floating Disc (http://www.hopetech.com/product/disc-rotors/) is there a BIG benefit above the normal std shimano single metal rotors? thanks Righardt
