Poet, I've been selling covered calls on SNDK with moderate success. I find the premiums are best with the stock is near a strike (20, 22.5, 25, etc) so I can sell an at-the-money call. The premiums are good and the stock is mostly stuck in the low 20's though I do see a bearish chart pattern at the moment. I began in June at $23.35 and my effective basis is now $17.55. I am currently short the Sep 20 due to my bearish feeling. Likely, I will repair if I'm wrong.
My other cc stocks and their basis after premiums received are ATML (8.31), NEWP (18.11), and VRTY (10.35).
