Re: holes in the kick drum....
It's all a matter of preference (isn't it always)? I use a 26"x16" Ludwig bass drum and no hole in the front head but that is the sound for me. I am fortunate enough to use a good sound engineer who knows how to work with me for getting that big Bonham sound. It does take some getting used to as I also use no damping in the drum either! The feel of the drum is altered totally as there is a lot of air to shift so once again down to tuning both heads for the right feel and response.
