X-3000 have a different interanal design as well so they should not balloon as much as a x-2000. I would say if your track is smooth but dusty the x-3000. If it is a little more rutted the X-2000 with the taller side wall will help soak up the bumps more. The X-2000 with good traction may feel a little wandery due to the taller profile. I have liked the X-3000 when I have used them. Give them a try.
