Ok, I don't know much about memory methods, other than browsing this thread a little. When I started, I did what came naturally to me. Sometimes I have trouble recalling my memo when trying to go fast. Is this an efficient method for fast singles?:
Each edge sticker has a letter (A through X). I'll memorize the edges in groups of 4. I memorize the group of 4 in really awkward ways. Often, I find myself memo'ing 2 and 2 in that group of 4. Example memo- OWVQ KGMJ AED. For OWVQ, I'd think of Pestvic punching me and me saying, "OW VQ." vq as in vic. KGMJ would be an extremely easy combo to memo as in Kevin Garnett Michael Jordan; 2 great basketball players. Then AED would be a weird way of prouncing AID. This edge memo would actually be very easy for me.
For corners, I just apply the letter to what face the sticker is on (W, Y, R, G, B, O) and remember the position of that piece. Example could be Y B B R W G O. I would try to memo those letters efficiently like the edges, but also remember their position around the cube.
I believe that I have more issues with corners.
