I started preparing my letter pairing scheme for memo some time ago, and I found what seemed like a problem. Using URB as buffer would leave me without an easy letter pairing letter, in this case it would be the letter D.
In that time I just ignored it and assumed using DFL as buffer and leaving the letter V unused would be the better choice, but now I doubt it will be. I mean, changing the buffer from UBR to DFL to avoid using the letter D (in the memo scheme) as buffer.
So, could you please tell me which buffer do you use for memo, and which letter it corresponds to? And which problems have you encountered with that buffer for memo?
Also, I may be missing some obvious fact, so please don't be mean when you start laughing at me =]
