I'm looking to replace my stock Kilo TT wheelset after 2 years of full-time commuting on them, and was wondering if someone could tell me the difference between these three Open Pro to Formula options:

32-spoke

36-spoke (why are these $10 less?)

I don't know how many spokes

Is there a 'best one' of the three? I'm about 150 lbs. and don't hop curbs on a frequent basis (not that I should...); so long as they can stand up to foul-weather commuting (Minnesota weather), I'm fine. I was hoping I could pick up a pair of Wabi GX410 wheels, but I don't think Richard has them in stock right now. Wasn't sure if I could find a sub-1750g wheelset (as Richard claims) for around $200 elsewhere.

Thanks!
