Using the SSFs is a nice alternative, but there's a few catches:
1) Very likely won't be able to do this in an IRA (I think some broker platforms would see the short call as naked, even though you are hedged with the SSF).
2) I don't use SSFs too often, but it appears the spreads are somewhat wider, especially if you get away from the near month expiration. I have only used them infrequently and that was on the front month.
3) You will have to monitor things a bit more carefully. If you are assigned early, you will actually be short the shares from the call. You are still hedged by the SSF, but I think you could be responsible for the dividend if you're not quick to cover your shares before it goes ex-dividend.
Just observations, so please correct me if I'm wrong.
