A perfect Tbird, for me, is a 60s one that hasn't been broken, is original (moving the G string bridge saddle north is fine), and doesn't way a ton. The best one I ever played was a 67, and I should have bought it. $750 in 1990. I have been kicking myself since, although I have made worse mistakes.
The best playing rev birds have all been broken and repaired, and I never wanted to pay a lot for a repaired instrument back a couple of decades ago. The best balance of weight and tone and feel I have ever played were Epi Embassy basses, which I consider to be Tbirds the way I consider a Ravioli to be an EB-2. After the Bicentennial birds, which have the horrid flaws of three point bridge and speed knobs, I have little to no interest. The more recent ones are fine, but I think you can do better for the money.
So, I never did buy one, but I will one of these days.
