I'm with Todd on this one. There are conditions where it's beneficial but not worth the risk in others. If the mast is built so strong that you don't need to let the rotator out in certain conditions then my uneducated opinion is that the mast is probably overly stiff creating fewer options for either depowering or increasing power to the sail/rig/platform.

I could be wrong but I'd rather have a mast that I can more easily tune using down haul, rotator, etc than a stiff mast that does not have to be rotated as far out.

Not if someone has a mast that allows both of these then they have hit home run and good for them.
