I picked up 3,000 feet of .065 for $13 at Wallmart. it was weedeater brand. I use the small stuff since it's cheaper and you can more on the spool. Furthermore, I find the thinner line cuts much better instead of "tearing" the grass and turning it brown. Also, the thinner line vibrates less. Just my thoughts. Oh, I just leave my line in a 5 gal. bucket of water and pull out what I need.
