How do you 'wear out' seatposts? Once the angle and position is fixed there's not much that you can do to a seatpost to wear it out. Now if the bolt isn't tightened properly you might 'wear out' the post but that's operator error not the fault of the post. Every post failure I've had (and I've not had many) have been because I did something dumb.

stormlight: No the Nitto isn't worth $95. Pretty generic post that's pretty but doesn't offer too much else. I'd suggest you look at a post that really offers something different. A Raceface Dues or Salsa Shaft offer clamping and tilt adjustments that are separate. Far better than a single bolt post like the Nitto...and both are about half the price.
