BTLOS 30mm wheels for pure climbing?

However, as soon as brake are used, then lighter wheels have slight advantage of getting up to speed quicker and lose less when brake applied.

I completely agree with the momentum part, this is one of the laws of physics. The other factor that comes into play is aerodynamics, which is why deep carbon rims are faster. So from a dead stop, is it easier to accelerate with lighter rims?
