Modern pad technology has pretty much gotten rid of these gases, so why are the holes still there? The simple answer is that they look really cool. But, this bitchin' look comes at a price. If not done right, the holes are a recipe for cracking when subject to heavy use. Under hard driving, every hole can become a new place for a crack to form."

lol your attempts are futile.
even they state that under "severe/heavy duty use" that its prone to cracking. we're talking about daily drivers here. stop n go driving, braking after 1/4mi drag racing will not bring the rotors to such danger zone. road racing is the where the brake system is really put to the test.
you need to read your own source:
For a street car that occasionally sees open-track days, there is no problem in using a properly engineered drilled rotor. You want to make sure the rotor was designed to be drilled, was drilled correctly, and that the holes have been at least chamfered to minimize stress and wear.
If you plan on hitting the track a lot and really punishing your brakes, then you will be better served to forego the holes and run a solid rotor. Besides cracking, rotors are also subject to heat-checking, which is the precursor to cracking. Heat checks are very small cracks on the surface of the rotor caused by thermal stress. While they are not a cause for concern (yet), they do indicate that the disc is not getting adequate cooling and are a warning sign that cracks may follow.
if you're gona try to give advice, i suggest you just post up that link in the beginning instead of stating your opinion. ppl are better off knowing about the brake subject as a WHOLE. HAHAHA your "source" is proving me right. thanks!
