I never had a problem with Union straps. I've owned the 2011 DLX and the 2012 Contact Pro. I used them with 2006 DC Super Park boots. They fit perfectly and I didn't have to adjust at all. I found it works best if you strap the upper part of the strap directly over top as you would the old classic style toe straps. When you do this, the lower part of the strap tightens up real nice on the front of the boot. It has never slipped on me before. I honestly don't see what people hate about them, unless I just got lucky with the size/shape of my boots.
