BOIL and KOLD - good idea, but one has to accept a much wider bid/ask spread and a time premium for going out a few weeks, but as long as one doesn't exercise an option or get assigned on one (when shorting the options) the transactions won't cause a K-1 to be issued.
I prefer to trade directly in the futures market, which allows one to select a futures expiration month and has tax advantages since gains are considered 60% long term.
