I love my 27" frame size Schwinn Voyaguer SP. I think this size was only available in 1982 but I've seen a few of them up for sale in the last year or 2.

+1 on tall bike sizing being hard to predict. I think when you get over 60cm that different builders take different approaches to making everything fit (probably the same for bikes < 52cm) and you really need to try a bike on for size to know if you will like it.

+1 also on the XXL Cannondales. I'm looking for one of those myself.
