I ride about 30 front 23 back and that's what I am used to so it works for me. I haven't changed my stance in years- been riding just a few years longer than what you listed. I started back then with back foot flat across and have been dialing it forward ever since. I don't ride fakie, except when just screwing around and on very flat runs, don't do rails, but still occasionally hit a jump in the park (but I am getting old for that). Maybe it's just what you get used to? I don't think I would like riding negative stance at all.
