You're right of course about removing the letter j from the most used letters. My strategy is to continue logging the inputs made with this system and adjust the mapping as frequencies change. If I indeed use the d-pad more often than j when using this system, the letter j will eventually be flagged for remapping. By making only one adjustment at a time the relearning effort is manageable.

As for diagonal inputs, I've actually done it and I'm still experimenting with it. I can accurately target 8 sectors when there is no dialing involved but with dialing I would stick to 4. I think a hybrid system that allows for 8 sectors but switches to 4 when I start rotating the stick would be the best of both.
