I got mine in June, and it was in my "B" line up. I only felt comfortable using small grouping with it. But one day I decided to put a 14 liner in it, and crank it up to 13.... and it worked great. It has worked it's way into becomeing my "go to" machine. I tend to line at 12v, 13 for big liners. 7 for single liners.
