I think this is really cool. And NOT taking anything away from OP or guys that can do this with large reels...
But when I jig, I've found that many jigs drop faster if you SLOW the spool down some to eliminate jig flutter... I'll either lightly pinch the line, thumb the spool on conventionals, or lightly grab around the spool on spinners on the drop. And I've noticed many, many others do the same...
So while I do appreciate the technical expertise and think this is really cool for bragging rights or maybe casting light weights... (jigs are heavy) I've never seen free-spool as a major factor with jigging reels. Decent free-spool, narrow spool, ZERO spool binding, smooth & powerful drag, good line retreive rate, plenty of line capacity, etc... are the things I'm personally concerned with...
For me anyway, this would just help me backlash the reel that much worse.
Really not hatin. Just sayin that a lot of guys reading this are new to the sport and are likely confused by all of the info and choices available... Decent freespool is important. But minutes of freespool isn't something to obsess over if you're just trying to pick out a new jigging reel IMO.
Maybe I'm just the Lone Stranger on this.
