Nothing is quite as thin beamed as the x series. That said, I have, and use, the x-dual gold and black 99/94 on occasion.
IMHO, the Angell has more in common with the Pro One (older pre-reincarnation) than the X series.
TC 97 is definitely stiffer all over than the X Gold/Black and has more pop. Foam filled so the feedback is similar, but I think you'll be much happier with the ball action.
