In what universe is the Open Pro at 390g? they're 430-440g approx, so hardly porky, rims weight isn't as important as you'd think, decent tyres, inner tube and correct pressure make the biggest difference (or tubeless).
If you're that anal about marginal gains, then the wider TB14 is the one to go for, Mavic's stick in the past while everyone is heading into the future.
