I know what you mean about the camelot wheel. Its quite constraining until you look beyond it into musical theory an realize theres much more scope for mixing it up.
For example; I found out recently that going from a A to B (or B to A) key sounds great if you add or subtract 4 from the number :/
At the end of the day though, you just gotta practice and find what works best for you. The camelot system is merely a guide, a pointer in the right direction.
