Dont buy the 50 yard spools! I only use tipups for panfish and bass on shallow lakes so i dont need a lot of line on mine, so i bought a few of the 50yd 15# spools for ease of spooling on my polars, one spool per tip up. Well, judging by the time the drill ran on each spool, they werent even close to the same yardage. A couple were 20 seconds, one was 40 seconds, one was 10 seconds, and one was about 30 seconds. Theres no possible way they were equal. The 20 seconds ones seem about right for 50yds, the 10 second one couldnt have been more than 20-25 yards.. Thankfully i had left a lot of old line on for backing with the short one!
The line itself feels great. Waxed, limp, a tiny bit of stretch, and pretty strong for 15#. Wouldnt suggest it for pike or big eyes, but should work great for me.
Moral of the story is always buy in bulk spools!!!
