>From a heat release aspect, and having had a somewhat recent furniture store fire nearby, I think you'll get hot enough fast enough to start popping heads very quickly. In fact I'd think that the 286 heads would be better at keeping the rings not really covering the fire from going off too soon. Not based on data mind you, just me thinking, and that's a dangerous course to steer by.
