If I were building them up, I'd use 2.0/1.8mm DB spokes on the right rear, and something thinner on the left, ie. anything with a 1.6mm thin section, with either 2.0 or 1.8mm ends. The front can be built with the lighter spokes since it's usually the same length as left rear. That saves both weight and money.

Resist the temptation to go heavier because that raises the minimum tension, and doing so on the left rear may force you to go crazy high on the right. FWIW, I very strongly believe that most or all the issues people have with Open Pros is due to excess tension. However, you may prefer to use so called triple butted 2.3/1.8/2.0mm spokes on the right rear. Since the major length is still 1.8mm minimum tension is the same.

Build them carefully, and if you don't crash these wheels could outlast you.
