Don't let negative Internet posts about hybrids worry you. The perceived issues with hybrids are few and far between. In fact hybrids are no better or worse for issues than any standard TT.
X2, I do not worry about a little consensation, I glance for it when packing up, when traveling the matress is standing up and the surface will dry up quickly. It's only surface moisture. It's usually almost dry by the time I'm packed up.
As for a heated mattress pad, we use them all the time in the cool weather. I have not seen it make any difference in condensation. It does keep me happy as I am warmer.
