I was only kidding. I have a strong preference for flat keys when reading mostly because the BEADGC progression of flats is so easy to remember. If you are only flatting notes, it is very simple. When you are reading music and you see a note within the key signature, you automatically flat it. Sharps aren't even a consideration. I stumble through the keys of G and D, and the other sharp keys, I avoid except when playing by ear.
Even at that, I can only read at a fairly slow rate.
I had commented on that on several occasions in this forum, so I was just kidding about it.
