Mate is looking to make his rigid Mtb a bit comfier due to some back challenges.
Basically just needs bit of flex in post.
I run Fsa carbon on my Kinesis xc pro 2 which also has carbon seat stays. It's v comfy.
He is over 75kg so the same Fsa post is no go for him.
However he is looking at Use post either carbon or Ti.
So, Ti offer a bit of flex or stick to carbon?
Carbon IMO, although I wouldn't touch a USE post either :p Has he checked out the Canyon VCLS ones?
I agree with fuzzywuzzy about the USE post, I had one a carbon one a while ago and it was shit!!
may i suggest a cane creek thudbuster ? awesome and under rated

In a similar situation myself (but under 70kg 😉 ), what's the beef with the USE carbon posts? Nearly bought one last week and still hadn't ruled one out...
I've got 3 Ti posts - 2 Van Nics and a Lynskey ran a carbon post on a c456.
I'd say Ti has a lot more 'spring' than a carbon post but you get a similar level of vibration damping with carbon.
on balance I prefer the Ti but you do have to be prepared to accept running a silver seatpost 😉
I've got an 8 year old USE carbon post on my road bike, it's still perfect.
