I have 200 yard...( 20 colors ) on both of my lead core rods....Only place I can find 200 yard spools is Cabelas....18 lb. test has the same weight lead as 27;;;36;;;or even 45 lb. test....But the 18 lb. is smaller circumference and will fit on smaller reel....I have one Penn and a Big Cabelas reel ....They will hold 200 yd....I use 27 lb. because of Lake Ontario trips...25 lb. test flouro leader of about 25 feet ...tied on with an Albright knot...Seven colors on Lake Ontario will catch the Steelheads in July
