Matt I understand your stance but the thick white smoke goes away. Sure more charcoal gets lit as the cook progresses but a little at a time does not seem to create that thick white bellowing smoke.
I always reverse sear my ribeye steaks. I put them on the WSM with the cooker at 185 degrees and then hit them hot and fast at the end to finish them. The first time I tried this method I dumped in my coals and smoke wood and with puffy white smoke going full charge I put my steaks on. They were cooked beautifully but tasted like a cigarette. I have NEVER put meat on until the thick smoke went away after that. I have had success cooking steaks and everything else with waiting until it went away.
water in water pan vs no water, low and slow vs hot and fast, lump vs briquettes... do whatever works for you!
