Mavic Open Sport Vs Open Pro

I'm building a new set of wheels, I know the open pro have a good rep, but i have a chance to buy a set of wheels with Dura ace hubs and Open sport rims.
I would assume if they teamed up the open sport with DA hubs that they should be of good quality, but i just want to make sure before i purchase.

What are the open sport like?
I don't mind if they are a little heavier than open pro's.
I'm a 100kg rider, wheels are 36 spoke F&R.

Thanks in advance

Open Sport is the budget, single eyelet version of Open Pro. OpenSport replaced the MA-3 which had lots of problems with eyelets pulling out/rims splitting. I have build more than a few of these with no problem. If the build is a good one, proper tension particularly, they should be fine. Best to spend the $ on the hubset anyway and the DA are nice hubs. Rims wear out, hubs when maintained well, rarely do .
