I have the Versa 11 levers. They got to me in a week from the US, which was impressive. I'm hoping to get the bike tomorrow. On-One have been great and allowed me to change the 'urban 11' build into a 'Versa' style build with dropped bars and mechnaical discs instead of the flat bar gubbins. Oh, I've also swapped the chainset to a 39 tooth'd one to get more sensible gearing (20 sprocket).
I should have my 11 speed Pompetamine Versa (Pro, effectively) on the road next week! I'll let you know my initial impressions...
