Those are light! Not familiar with ROL but they look very nice.
I put a 24 - paired spoke Velocity Thracian on the front of my long wheelbase 'bent but am hesitant to match it on the rear - the weight distribution is heavily to the rear and I am no lightweight. Leaning towards a similar Velocity wheel with 36 spokes.
