Hi chaps, first post ..
Not fired a tuned 97 - had a shot of an untuned one - bit twangy.
Not tried the TX200 either.
Did have a HW80 177 i hunted with back in the day I loved.
I now have got a Pro Sport 177 - vmach spring and guides, Vortek O ring seal (quantum greas on it) Shoots real nice and use this for HFT. Only thing i dont like, the trigger just aint as good as the Rekord unit.
The best gun on my experience for looks and performance would be, a tuned pro Sport with a rekord trigger unit in it - a nice little impossible hybrid, that i think would be hard to beat -
