Decided to give Wicked Good Lump a go after reading all the reviews on it here. I've been using nothing but Royal Oak since getting my egg in July 2012. Been pleased using it for the most part but am not opposed to trying something else.
Ace Hardware had a 10% coupon code and bought it from them with free shipping. According to Wicked Good's site there are no dealers here in Ohio. Who Dey!
