I can very much recommend that you try a V-Mach kit from Steve Pope. I have recently installed them in both my TX200 and HC and am very , very satisfied with the results. Steve Pope is also extremely helpful should you have any questions or need any help.
I am living in the 24, so if you are anywhere near you are welcome to come and try the guns for yourself, I am also a fly fisher by coincidence.
Cannot comment on the short stroking but, would not want to change my TX's in any way further now.
With kind regards
