Today is the day I get my Egg. I have decided to go really wild and cook "Dad's delicious big green burgers" from Roger in Charleston. My son is anxious to test this thing out so I thought I would do something simple.[p]My Egg is a Large demo unit from the showroom and it came with the daisy wheeel. Should I look at purchasing the Dual function top in the near future or can I do everything with what I have.[p]Thanks for all your help.
