smoking first chicken tonight

Im gonna smoke my first chicken tonight on my new smoker. It will be my maiden voyage for chicken on a vertical water cooker. I usually just inject with creole butter and lightly rub with creole spice and olive oil the skin for crispness. All my experience is with an offset cooker so is there anything I need to know about a vertical water cooker when it comes to chicken?

leaves me more time to drink beer.....
