Care to share about what holes you're talking about. I may pick up a M-Audio HDH50, maybe it just has different venting config inside compared to the AKAIs by default. :)
EDIT: Wait isn't these the AKAI you've got? Seems like so as it's the same specs as the M-Audio only 1 EUR difference between them (AKAI 1 EUR cheaper).

Maybe it's the pics fooling but the M-Audio's pads do look slightly higher quality.
