I have built a 23mm tx to compare it to the ally pistons I make, The shot cycle is very similar, the cocking is easier, and the sight picture movement similar, very difficult to to choose between the two, next step for me is to go down to 21mm comp tube with the standard tx mk3 stroke and see what that's like
