I had two. The first one met the manufacturer’s states shot count the second did not. As is well known, the ST barrel was designed for the jsb pellets. The deal breaker for me was that the accuracy on both of the guns suffered when shooting at the lower power settings. This essentially made one of the features I really wanted null and void. I don’t seem to have that same problem with an older version cyclone and s510, both of which have Lothar Walther barrels.
That being said, I am really looking forward to the STX system and anticipate that will make the barrels less pellet and velocity fussy.
i would hold out for the dreamline if I were you.
