1) Yes, I have tried gangsta style. Hits were OK, I just kept getting hit with brass. I tried two guns and the results were better than expected, although still pretty bad.
2) I rarely clean them. My dishwasher is an 11yo girl that can't always rack the slide on my 1911s, so I dont make her clean them.
3) Never tried Bra Carry, and since I dont wear bras I doubt I ever will. Ankle carry doesnt work for me, neither does mexican style with the magwell pointing to my right.
4) Teacup & saucer? Never tried this.
