Hi Tony.
Yep. More than 1 way of skinning a cat to be sure.
In fact the best shooting TX I ever had, used a HW mainspring.
This 95 has a reflex slimtech style silencer fitted.
Its a little chubby in my mind at 25mm OD, and before actually finding out just how well the 95 shot, I'd planned on turning the OD of the slimtech down from 25 to 20mm (then getting it reblued).
I have a sneaky feeling that the extra weight that the slimtech currently carries, is part of the reason its shooting so well. I need to field test it as soon as I can and if its anything less than perfect, the slimtech will get turned down, and I'll definitely have the vmach spring out and go my normal route.
