Actually I meant what I said:
I guess I figure that if I am replacing something I should replace it with something that will weigh less because longevity for a seat post is mute.
as in:
I guess I figure that if I am replacing something I should replace it with something that will weigh less because longevity for a seat post is undiscovered/unrecognized/silent.

ergo - No one really knows how long an AL/Steel/TI seatpost will last. Which is why longevity is undiscovered/unrecognized/silent.

I agree that either word could be used and one may be more appropriate than another.

Back to the OP:
Thompson Masterpiece: 158g for $150
Fizik Cyrano: 221g for $125
Woodman: 144g for $135

Seems like all things being equal the Woodman wins out. I like the Fizik because I can turn it around for a TT position, but I do not TT or see myself TTing. The Thompson is nice, but the Woodman is both cheaper and lighter and both are AL. Granted the Woodman uses a carbon cradle and Thompson does not.

Food for thought I guess.

I have a legal background and in my field moot and mute are common words.
