It is best over direct coals and I find the WSM works great. You get the flavor from the drippings but not all the char like when using a kettle.
Chris, next time use less coals (maybe half chimney for the 18" kettle). I'd also bank them onto one half of the grill, that way if you get a bad flare up you can just move the chicken to the side without coals to prevent charring.
