Yes, Wayne, it's fairly conservative. I get on the UNG in spots here and there, as an ETF is so efficient to enter and exit. A problem with it though, is if the market is in a steep contango, the fund is fighting an uphill battle in exiting the near-term and buying the more expensive long-term contracts. I would say if you're already set up and familiar with a good futures broker, then go ahead and use the actual futures.
