Open pro/Ultegra vs Planet X

I'm looking to upgrade the wheels on my giant ocr to something a bit lighter than the stock ones that came with the bike. I had been intending to go along the usual lines of open pro's on ultegra hubs but I noticed that planet x are now doing some good deals:

I prefer the Planet X "B" set since they are the lightest of the three and look a bit nicer, but my concern is that I’ve been told to look towards 32 or 36 spokes to carry my 200lbs frame. However I've read reviews from plenty of people heavier than me who use 20/24 spoke wheels without any problems. Also, as more of a sprinter than a climber, will all low spoke count wheels inherently flex to a degree?

Also, does anyone have any comments and in particular, experience of using the new planet x wheels?

Thanks
