I see your point. I just thought that many smaller holes, giving more surface area, would dissipate the vibrations better. It is a hell of lot smoother while driving, almost OEM feel compared to be before. Its just the super low idle that ruins it.
Before you'd need to hold it at just over 1k to be smooth, now when it 'fast' idles naturally at 850ish is bearable, but then when it drops down to its normal of 550ish its still hideous.
