suspension, suspension, suspension.
If money isn't really an object, go with the marzocchi Z1 series. it's all the quality you can buy, with the best airsprung system you'll find (uses higher volume, lower pressure... better seal integrity). the rigidity, travel, smoothness.. it's all there.
if not that, i'd suggest the sid 100 (it's six grams lighter than the marzocchi)... it's somewhat limited in adjustability and rigidness, but has a nice compression feel. And, it's about 250$ less.
