Me too in my Mk1 TX, although I have one of Jon Budd's TX's with a lightened steel piston, and a HW adapter head running at about 77mm stroke and that's not bad at all either.
tbh I know some people love mucking around with the internals of springers to try to gain an edge and that's cool, I'm glad there are people around like that.
When it comes to knocking over targets in a competition though, I don't think it makes a huge difference what you run internally, it's like any gun used in FT. Whatever you've got make sure it's setup meticulously and it'll knock targets over.
