But I wouldn't miss the opportunity to keep practicing in other keys...... too much familiarity with just one key makes you lose an incredible variety of fingering 'tricks' and licks that can only be done in other keys......

Perhaps a good practice regimen might be to say to yourself 'OK, for the month of September I will ONLY play in the key of D, then in October I will play in ONLY 'G'' and so on and so forth.

Abandoning ingrained fingering from one favorite key for a good few weeks will help you develop your chops much faster than just playing mostly in your favorite key, and only occasionally trying something different........

Give it a try, it's easier than you might think.....!
