I need help setting up my line with my reel, I know how to spool it...READ DETAIL BELOW?

unfortunately you opened a whole can of worms with that question. excuse the pun. ok now to Business. the line choice you make depends on what bait you will more than likely use. mono floats and is great for top water and shallow running cranks.floro sinks and is less visible under water. use this for deep divers and jerk baits, texas rig, or Carolina rig or even finesse or drop shot. braided line is best for heavy cover or larger fish. all of the fish species you mention all require different set up. you wouldn't use the same set up to catch crappie and cat fish. if i had to choose one line out of them all i would go with a 12 or 14# floro. that should cover large mouth and small mouth. for fishing crappie i would go with a 6lb floro. for cat i would go for a 35lb braid with no leader. i don't like leaders because of one simple rule. your line is only as strong as your leader. if you tie a 6lb leader to 35lb braid you will only have 6lb of strength. you mentioned that you caught all these different fish i ume with other people's Equipment. you must have noticed that the rods,lines, and lures were all different for each type of fish?
