The thicker the heat baffle plate, the more even the heat should be, and this means more money. This also means more weight if you move it around a lot. I kind of like the normal offset so you can have dual cooking zones. But to each their own. Maybe a hybrid is the best option like how many people modify their offsets, with movable baffle plates to set up the cooking zones as necessary for your cook.
