They’re good wheels, I don’t think you’ll regret it!
By the way, they use Shimano proprietary straight pull spokes, and evey Shimano wheel has a slightly different version of the spoke (length, diameter, colour of nipple), so they can be a pain to get hold of because nobody carries stock.
Not that I’m expecting them to break, but if you’re like me and like to be prepared, might be worth picking up some spares now.
Theoretically, any LBS with a Madison account should be able to order some in for you, but I’ve heard stories of it taking months and charging about ten quid a spoke, so I got mine here when I was ordering some other stuff.
