We just got our first tandem this summer, but pretty much, if both of us are riding, it will be on the tandem! It's just too much fun. It's just an older khs sport that is probably too small for us as well, and I don't like the upright riding position, but I'll still pick it over the singles. Now we're saving our pennies and dimes for our next tandem - with drop bars, more gears and 700c.
