I didn't reply to you sir, I replied to the orignal poster. I appreciated your answer.
here is the faq poop on it from RMMP 9a faq to which I have contributed a small bit);
' An opening in the center of the drum may commonly have less low end and more beater attack than an off-center opening. This is a matter of personal choice, and you should listen to both before choosing. The trend in recent years among manufacturers is to put a small (typically 4'-6'

off-center opening in their resonant heads. Ten years ago, pre-cut openings were typically larger and more centered. Today there is also a resurgence in closed heads. Again, a matter of personal preference. Be aware that most drum stores will cut a head to your choice of size and placement. You can also do this yourself.'
My take on the matter of why Lars Ulrich or any heavy metal drummer would use the center position for the hole is that they desire for more head/beater attack/click to escape from the hole. I personally think the response of the drum both sound wise and pedal feel wise is better with the off center positioning. Just an opinion.
