proud owner of a medium egg but I have experienced some problems with doing long cooks (i.e. boston butts). I usually have to bend a coat hanger and stick it up through the draft door to unclog the ash from the bottom grate holes when I notice my temp starting to fall. I've talked to several people who have large eggs and they never have this problem. I've seen the BBQ Guru Turbo Grate advertised and I was wondering if this might be a good investment for me. Thanks!
