Mountain Biking - suspension seat posts

a new suspension seat post is an option that I have been mulling over for some time now. I was looking into a nice titanium post to save weight and take the edge off. However cost is high, I was looking into Thudbuster and the other styles....I wanted feedback on either system and is titanium really gonna give me some flex?
Thanks

I wanted feedback on either system
I've used a telescopic one and was dissatisfied. Heard good things about Thudbuster, but I ride FS now.

is titanium really gonna give me some flex?

I've seen alloy posts with a lot of extension flex under heavier riding companions while climbing. The flexing movement (fore and aft) is no remedy for the spanking the saddle is trying to give you. Ti is cool looking, but is no substitute for a suspension post, FS, or a smoother trail.

I rode a Thudbuster for a few years. If you're looking for something to just take the edge off some of the sharper bumps and the regular trail chatter then it does the job nicely. But you definitely know you're still on a hardtail - it's no substitute for a FS bike (which I still can't afford :().

I originally bought it for commuting and it was great for that. But I found that when I used it on the trail it probably made me a touch lazy. I was sitting for things I probably should have been standing for. Now that I've gone back to a normal seatpost (Thomson Elite FTW!) to save weight it took me a bit of time to readjust.

What he said. If on your hardtail you think you need a suspension seatpost then you should be standing.

fellas, I did ride a FS Speciaized for years but hated the dam thing never fit well. I am old school Gary Fisher HT now and luv the agility Butt/back get sore I do sit and ride big gears through stuff I just need a small amount of relief,,,The post I have suxs always gets loose so I need to readjust mid ride....Thudbuster is cool but heavy and $150 Telescopic USE seem good reviewed very well ti I was hoping do to the flex would be enough how ever I never rode on.\
I am leanin gtowards the USE for th erock gardens type of stuff
Thanks.

I have a Thudbuster on my DH biks and it really takes the edge off of those big hits.
