Btw, if you want to test out some of the soaps on mention in this thread, you can get samples from Shave Dash - great place I bought a lot of things there myself. They have most of the things mentioned in this thread aside from OSP, who you can get a sample of from Connaught (who also sell many of the ones mentioned here but in tubs).
Welcome to the forum, can't help you with the more exotic soaps I'm afraid as I'm new to DE myself and using Arko and Palmolive sticks at present till I nail my technique.
