As for leather strops, all leather is not created equal. Tradional barber strops are made from vegetable tanned leather from horse butts. (no joke). They are very thick and very hard so that the leather doesn't give when a blade is dragged over it. The "give" thing is very important but, you can accomplish the same thing with a belt if you pull it very tight.
Personally I prefer a flap off a plain ol' corrugated cardboard box. Plain brown cardboard is mildly abrasive and works excellent as a stropping material. Just lay a good sized piece on your bench or table for support. You may want to clamp or tape it down so it doesn't move while you're using it. Strop diagonally across the ribs in the cardboard, keeping firm blade contact but don't push down hard enough to crush the cardboard or even compress it.
Brandon,
Yes you can do that with the Lansk...(oops)!
You'll probably need to jump up one angle slot higher to adjust for the added thickness though. One often overlooked thing about stropping is that maintaining a consistent angle is just as important as it is when sharpening.
