knowing shimano spool quality, i always stripin lines out after each fishing trip.
Just imagine, 2 stella 8000, 1 10000FA, 1 SW20000PG, 2 SW10000XG, 1 SW5000XG, 1 Dogfight....tough winding....but for me that is the only way NOT to see any corrosion on stella's spool.
Winding in back, i just used the tension from Daiichi winder which give me enough tension to pack-up my spools.
