dunno if you were referring to my comment:
cheap seatpost that fits > grand mighty seatpost with shim > ****ed up frame
but i was referring to his question:

i was posing my opinion that using the right seatpost is best. second best would be using a shim (which will work, but imho is less than ideal.)
the worst idea would be to clamp a 27.2 clamp onto a 26.8 post with no shim. not only does it deform your seat tube, but it puts uneven pressure on your seatpost, causing you to have to torque it down even harder to keep it from slipping. i've cracked a seatpost and stripped an internal seatpost binder bolt this way, but of course, your results may vary.
with a shim there is less contact area and unless it's cut PERFECTLY it will probably scratch your seat tube. i still believe that a cheap seatpost that fits would be superior to a nice post with a shim. but a shim is better than a ****ed up frame. that's all i was saying.
