what you fish for , and how you fish means a lot. For stripers, 150yds is the minimum for me. A huge striper will peel off line, they run like all salt water species. Bass fight it out close and everywhere, deep. airborne, what ever. Musky the same they will make one short run, and then fight you close and under the boat.The champ in freshwater is the king salmon, long runs will spool a lot of reels.I use braid, so 20/8 will give me plenty of line, and a lot of stopping power.Bass fishing, 50 to 75 yds should do you as long as you stay near the spool recomdations. I like to troll a lot so I have a lot of line out sometimes, but species should be considered.
