I am choosing between these two wheelsets.... can anybody list for me the pros and cons of each? Which setup is lighter? I read somewhere that the Cosmos rims are essentially the same as Open Pro rims. Which setup is more likely to stay true for a longer time?

I've had a set of Open Pros w/DA hubs for over a year now. They were trued once when I took them back after 200 miles of usage and I will have them done next month with my yearly tune. These wheels are not the lightest, nor the heaviest, but you can ride them daily (I had over 6,000 miles last year) and they continue to perform without maintenance. I just purchased another set (ultegra) for my Cannondale.
If I were to race, I would consider something lighter.
Unless you're extremely competitive, the Open Pros should do well for you.

I have a set of Open Pro's laced to Campy Daytona hubs and they are very strong wheels.
For racing I prefer to have hand built wheels with standard components that are easily replaceable. Some of the factory wheels are a nightmare to repair when things go wrong. Rolf comes to mind..

does'nt matter, my opinion is unchanged. I feel that hand build wheels are better than factory wheels.
Best investment you can make.
go for 28 spokes, bladed or DT revolution. Them wheels will be light light light
Did I say they'll be light

open pro's are as bomb proof as you can get. if your roads are patchy them open pro's are the way to go. (imho)
and they are easy to back off and retension if you do have problems (non-drivetrain side like most)

I have a set of OP's w/ Ultegra hubs I bought through Colorado Cyclist for under 200 dollars w/ shipping. They have been great. Had an initial truing after a few miles were put on, and they have been true and untouched for over a year now. I also have some OP's with DuraAce hubs that i got built from Quality. One truing after 3 years and about 7500 miles and they are still going strong.

The DuraAce hubs feel a little smoother, but other than that, the OP w/ Ultegra wheelset is a great choice for a dependable, decent wheelset for a great price. I would get them again.
