I've always played using internal view since my first few laps done with the first WipEout. External view simply won't get me that pure and fantastic high speed feeling which I am experiencing using internal view.
After more than a decade of internal view I found that I simply cannot switch back to external. I've tried to switch views with the introduction of BR in Pure and after some insane and mind blowing stunts in Freeplay mode on Vohl Square but external view simply doesn't work for me anymore. It's always me screwing up badly because I'm not able to determine the right points for turning and thus I either end up crashing into walls a lot or correcting my lines with some heavy airbraking when I use external view. It seems this is a bit like marriage for me - there's no turning back once you've made up your mind. And even if I get a headache after a phantom ride at Vohl Square or after a triple BR at Khara Descent this still feels better than a lot of wall crashing or loosing speed due to too much airbreaking.
