Demo'd the Tbird today, and had a blast. It was a fairly short (10 mile) group ride, so I couldnt push it much but I got enough of a taste to form a favorable first opinion. Very torquey, good brakes and good center of gravity. Felt heavier than the America, but that did not really bother me because the weight was low. I can definately see one in the future, but the America is paid for now. The Tbird was fun, but not enough to change my plans. I am still gonna do the big bore this winter, and will be keeping her for at least a couple more years.
