Ritchey Pro Carbon seat post

$64
light weight at 235g
vibration dampening (really excited about this)
obvious upgrade from Kalloy aluminum seat post
would match my Ritchey headset
but a little sleeker looking than I'd like for my plain ol' Surly.

or

Salsa Shaft seat post

-$34, very affordable
-favorable mention on peterwhitecycles.com
-"Two-time winner of the Bicycling Magazine Editor's Choice Award"
-more lightweight than my current Kalloy at 260g
-Aluminum
-would match my Salsa Liplock seat post collar
-fore/aft saddle position and tilt independent of each other, very easy


What would you pick? Why? Any other suggestions for a an affordable, under $75, seat post, aluminum or carbon? Is carbon really that much better than aluminum? Thanks.
