B.E. ... I've used 4lb test Vicious Panfish hi-vis - 4lb test Stren Gold - 4lb test Mr Crappie Super hi-vis (USA made version) ... and have no complaints. But, like DB4D says ... everybody thinks THEIR choice is the "best" (or at least the best they've tried)
Just understand, going forward, that reels with very small diameter spools, like those of microlite & UL size, are going to set most mono into memory coils ... after having the line on them for a length of time. Occasional re-spooling with new line, or pulling out a length of line = to 2x a normal casts distance & stretching it will remedy that, somewhat.
Keep your filler spools of mono OUT of the Sun & heat. It's not wise to keep your line in your tacklebox, vehicle or boat compartments, or anywhere it's subject to excessive heat or direct sunlight.
Occasionally dragging loose line behind a boat at idle speed for a few minutes, or through the grass in your yard, will generally untwist the line. Occasionally, jigs will spin in the air when being cast, and spin when falling on slack line ... and then you reel the line in, with little to no tension from the very small weight of the jig ... and the twisted line gets put back on the reel spool in loose loops. Eventually, you'll make a cast & a whole wad of tangled line will come off the reel spool
... or a loop of line, from within the lower levels of the line wraps, will twist around the line coming off the top wrap
... and then you'll have to untangle or cut off the mess. Performing the previously mentioned untwisting methods will reduce those aggravating moments (which always seem to come at the most inopportune times).
