I've had two TXs and a Prosport , all in 177, and they were good, but very hold sensitive, and I never really liked the CD tigger.
I was deterred from trying them in 22 because of the long stroke and my stupid bias against that calibre. People said they were sluggish and slow in 22.
I often wonder if I would have preferred them in the larger calibre.
All mine were in walnut stocks. Even the beech stocked ones are about 400 quid these days.
Guess I'll never know.
