RockShox Reba is an option for agressive XC/Allmountain.

Re other thread: you possibly might be able to keep your current fork, buy a new 'spring set' (that can change the travel into 100mm from 80mm i think), and get the LBS to put it in for you... I know a few of RockShox forks can be changed like this ( i think i'm right in saying changing the springs), but i'm not too sure about the fork you have now
