I am not saying that you need a guru - but will say after using one it makes things so much easier I never want to go back.
Besides being able to sleep for hours during my bbq w/o needing to go check the temps to make sure it is still stable. It is really nice to light a pit - see it is stable, and within 5 minutes go to sleep for the next 5 hrs till morning. Then there is stick burns. Try to stabilize a uds burning twigs - with the guru I set the temp, and can walk away, it can micro manage the burn.
