My Smokin' is drilled 2E, and is in box finish, and it works well for me on conditions that have broken down somewhat. It seems that the key to success with the Smokin' is making sure you have enough friction on the lane; in box finish, it *hates* oil.
I should also mention that, of the people I know out here who have tried changing the cover, none have had much success with it on oilier conditions, even when scuffed.
