I suspect that buy and hold will outperform since there will be very long periods where you are out of the market while waiting for VIX to go above 30.
My only point is that if you do whatever you normally do....but then buy SPY (or SSO for more leverage) when VIX goes above 30 (including using margin if so inclined) and then sell when VIX goes below 20....you will increase your profits.
