Always fun seeing another startin the slide down the other slippery slope.
As long as you're alternating bowls with the cobs, you'll be fine, you only have to worry about letting the cobs cool down between bowls. Thats the beauty of cobs, low maintenance and dirt cheap. When the sucker burns out(there's no way getting around it, it will happen, no matter how much you cottle it) its $5-6 to replace, as opposed to burning out a nice briar which will typically run 10 times that, though then again, a briar can last a lifetime with proper care.
