++ on TG. Our experience also.

We bought our tandem used a few years ago. It's previous owners were in Texas. It had about 2000 miles on it, and came with what were probably original tires: Gatorskins. The rear tire was worn to a rectangular profile, probably not too far from the cord. It didn't have a scratch on it. Nary a cut. What does that mean? Hard rubber. What's the tradeoff? Traction. A very experienced buddy of mine had a serious accident on wet Gatorskins this winter. And they rode like bricks, totally unlike the lively (and fairly easily cut) Tricomps we run now. So there are tradeoffs to everything. It's just good to know what they are.

I've heard that Paselas aren't that great in the wet but fine in the dry. Schwalbe Marathon Plus are very common on tandems.
