KH Seats

I've had a Kris Holm seat for about 6months. Recently it's started to
develop a lot of flex and makes various creaking noises when pulled on.
I'm not a particularly abusive rider, I do mostly freestyle and a bit of
light trials.

I was wondering how common this is, so I thought I'd start this thread
to do a little informal survery. Has your KH seat become suddenly more
flexible since you bought it, and if so, how long did it take to happen?
Any other problems with the seat? Please reply even if you haven't had
any problems (including how long you've not had any problems for ).

Note, I'm not criticising this product, I have found it excellent in
terms of comfort and very practical for hopping etc. I just thought
that now it's been out for a while it would be good to get an idea of
it's durability. If we find, for example, that a lot of people need to
replace their seat once or twice a year, that would be useful
information.
