I am using 30 gauge. I apologize to the many that have helped me in this thread and probably told me all of this before. Problem is I am also getting used to two new toppers (Lemo and Taifun GT2) and so much more to learn ago. (I was perfectly happy with Taifun GT1's for over a year) anyway all this new stuff to learn AGAIN....shhhez I just want to 'not smoke' not redesign the wheel
