clutch kits

there are two clutch kits available. The extreme and the economy. Now what would be better for me? I run 26" mudlites and play in the mud but normally we ride hard pack, wooded trails, technical stuff, and hit the mud holes before we head home. I dont think i would need the extreme one because i'm not running huge mud tires and think it would make it somewhat difficult on the technical stuff. What do you guys think?
