I did one not too long ago- the recipe might be in my dropbox. PM me your email, and if I can find it, I"ll email it to you. Do you have Beersmith? Or would you like a text file?
I don't remember where I found it initially- maybe it was on this forum but I just don't recall.
I don't know if it was a good clone or not- we don't have Mirror Pond available up north, and I drank it down here in Texas and was trying to remember if it was the same or not.
