I know I asked in another thread, this is just to learn for me. I have a lot of learning to do when it comes to fly fishing and all the different lines and what they are used for and capable of.

Not in a hurry here, not going to be buying a bunch of different lines anytime soon. Need to learn to land a salmon on a fly rod before I can even think I will have a chance at landing a Chinook on one.

Does anyone know of a detailed online article that explains all this stuff in basic terms? Anything that I can use to learn the basics of sinking lines so I can start to learn them fishing for trout in lakes where I don't have to worry about a #40 nook whoopin me let alone a #10 steelhead.
