if the bark comes off easily, take/knock it off, otherwise don't worry. soaking wood really only applies to chips. not enough water there to matter. as to soaking chunks, alton brown did a test. he soaked wood chunks at differant intervals. he measured the weight starting with a dry piece. after wood was soaked for over a day, the amount of water soaked up was so little as to make no differance. wet wood would be to bitter for small smokers like weber kettles and wsm's. but really, the only test is what you do and if you like it or not. to many likes and dislikes out there to have one set rule.
