I have the new Funnel Flame Zone setup on my 2 Star. Not sure I buy the argument that it adds to the smoke production as my old 2010 1 Star had none of the latest and greatest and it put out SERIOUS amounts of smoke! As far as quicker heat up times... absolutely true! As far as better pellet consumption, not sure... but, I have never been disappointed with MAK’s pellet consumption. As far as how to use it, yes, remove one or both of the covers when grilling. No, it’s not like searing over a bed of raging lump charcoal, but it (IMO) is one of the best everyday grills I have owned... and I’ve had my fair share. Also, the setup will look much different than what you are used too... it will completely replace your current setup:
Also, you definitely don’t “need” it, but the MAK searing grates (I have 2) completely changed things for me. Being we eat with our eyes first, that addition changed things big time for me.
