2.2 with a 12oz bag. I used 1.75 for a year or two, it cut my hands when pulling the rope through and it would only last about 6 months before it began getting wind knots. The 2.2 might cost me 10' on total range but I can still shoot it over 100' when needed. And the 2.2 doesn't get wind knots as easily. My current line is almost 2 years old and is just now beginning to knot up on me.
