I paid for my seat on 26 January and it's being delivered today, just after my bike has been collected by the dealer to fit the new wheels and exhaust. I'll probably take it along there and see how it fits. Good communication through the pre-order process and they were happy to keep taking different pictures and show comparisons to the standard seat. I ordered the flat seat but asked for it to be rounded off a bit on the edges.
They reckon there were some issues with a change of screws and the hole size for the current bike and apparently it's sorted now, so it will be interesting to see how well it fits and how it sits on the bike.
I'm not posting to make any points, etc - just adding to the thread with my experience of this Company, which may or may not end up positive!
