I've used one of those VCLS split posts on my Mason for road ultras for a while. Bit of a faff but I miss it when I went back to the Thomson for a bit. I now have an eeSilk on it for reasons I can't recall (it was on the gravel bike).
you have creaking/slipping problems with the vcls post? i had one for a while but thing could not perform the core function of a seatpost despite being overtorqued.
