I went from doing a 3 pass shave to doing 2 pass shaves (WTG, XTG), and this cut down on irritation. It isn't quite as close as the 3 pass shave (which was pretty much BBS), but it also allows me to shave every day, which is always nice!

I also second the idea of reducing blade angle. 30 degrees is a recomendation, not a hard and fast rule. Experiment a bit and find out what works for you. I was shaving with too steep an angle for quite some time unknowingly. My shaves improved quite a bit after adjusting angle.
