I don't think you can get the Moto TT frame anymore. It's been out of stock like forever. The Wabi is nice, but it's not track geo like the Leader, if that's what you like. The more I ride my Leader 721tr, the more I like it. One benefit of the long top tube is that there is less toe overlap with the front tire, but I still get track geo with a steep head tube angle and small fork rake. I think the Leader aluminum frames strike a good compromise between light weight and durable dent-resitant design.
