Wheelset options, advice?

10mm is big difference and you'll have issues with hub slipping in the dropouts. From the site:

We've featured a well-balanced range of wheels that aims to appeal to all users, whether beginner or professional, and by honing in on a small selection we can keep prices low. However, we know how personal this decision is, so if we haven't listed what you're after, drop us a line and we'll quote you a price as long as our suppliers can provide the components.

I suggest using a 130mm hub and mavic open pros are an excellent value, quality rim
