Might be time to overload the leveraged funds as opposed to the buy/write funds. This market is showing no signs of backing off significantly and with the buy/write funds mostly at premiums (even ETW is close to a premium!), I think you've seen 90% of the move in these funds. The sell call strategy will limit the upside if the markets continue up.

The other alternative is the Eaton Vance leveraged CEF's ETO, EVT & ETG. Pay monthly and are at double digit discounts, mostly because they cut their dividends at the beginning of the year. Their NAV's have recovered significantly and I wouldn't be surprised if they RAISE their dividends if this keeps up. Just went ex-div but I would keep an eye on them over the next month.
