I haven't fished with it, it's to big for my type of fishing. I did play around with it in the back yard before I tore it down. Not sure what size line was on it, but it was old, heavy and curled badly. It appeared to work as it should, but with that old line I couldn't get it to cast very far. It cranked in alright and the drag worked. After I took it apart I never put any line on it. Like I said in my earlier post, I liked it's simplicity and believe it would work fine for heavier fishing. If your going to use heavy line a reel with on oscillating spool might be more efficient. When I panfish 4-6lb line is the biggest I use. When I catfish I prefer bait casters.
