Depends on what type brakes you are going to run up front. The Fox disc/v-brake compatible forks are harder to find, the disc are usually easier and a little less expensive. If you want to run a Rockshox SID (2001 to 2005 w/lock out) up front, they are usually significantly cheaper and easier to find, if you can live with the 28mm stanchions versus the 32mm stanchions on the Fox. I have both SIDs and Fox RL on my bikes, and they both ride well. I’m sure there are other options, but the air forks ride the best in my opinion.
