Get both of them, lol... I have both, personally I like the 66" Buffalo way better than the TC.
I almost never see a Buffalo for sale, can't say that about the TC. Big Jim would have to say if that is due to shear numbers of TC's being sold or if people just hang on to their Buffalos.
One thing for certain, which ever you go with, you will receive a very well built bow that is a performer.
The good thing about a bowyer with a waiting list is you have time to change your mind a few times. I know that I wore out the slide show of his bows on his site.
