Dependingon the IV's of options involved, there are probably better ways of capitalizing on a mkt call of a slow grind down much like the mkt call involved in a covered call which is a grind up. For instance, you could buy OTM calendars on the lower strikes, maybe an asymetric fly where you buy 3 A puts, sell 5 B puts and buy 2 C puts to take advantage of the skew. positives are limited risk, theoretical advantage coz of skew and no blow-up risk. negatives-pain in the ass to leg in/out, commish.
