I have the gel seat and I'm perfectly happy... except when the temp is less than 4degC.... then it's rock hard.
Ray has a Corbin and is contemplating getting it tinkered with - as it's still rock hard. Bearing in mind he had it on the America before he got the Speedie, he's had it a while. He actually said it's causing him pain...
To me there wasn't really a choice. To get one from the US just was financially not a choice. I got my gel seat from my friendly dealer with a fair bit off.
