Most bass tourney guys that fish jigs around any sort of cover have their drags turned completely up so that no line comes out at all. If your targeting purely largemouth in the northeast, which means realisticly no chance of a LMB bigger than 10lbs, and you don't care about other species (tournament angler), there's no point in having any drag. You aren't going to hook a bass that can break 17lb+ mono or 30lb+ braid.HOWEVER - I set my drag on all but one of my casting reels - My frog rod - a7'6" XH rod with a 7.1:1 retrieve ratio and 65lb test power pro, ain't nothin' where I fish that is going to snap 65lb test power pro.
I believe drag is one of those thing that if you using a super line it can be a thing not to think about but with mono it is a key and as pointed out old line it is a must , as for do i us it yes and no my heavy line rod no on my lite stuff yes but that is I us fireline on my heavy rods and mono on my lighter stuff and as how is set my drag I just grab the line if i can pull it and the drag slips freely i think that good but some time i still have to loosen it one bigger fish but that's what it is for
I love the sound of my spinning reels drag, need to get it in a ring tone
