Nathan...there's no manufacturer of which I'm aware that "require" use of an anti-sub belt in their harness. Most offer it as an option, but it's not mandatory. If you plan on going to the track, however, every sanctioning body I know of requires at least a 5-point harness, and some a 6-point. Makes sense to me to go ahead and install it now, while you're in there doing the work. FWIW, I've installed 5-points on both sides of #770...and I wear my anti-sub belt whenever I'm in the car. I figured I paid for it, might as well use it. Plus, I like the security it brings me...I like being snugged into the seat.
Tom...when I replaced my OEM belts (Deist) with Simpsons, I went to the cam lock buckles. After seeing the ejection at VIR ...it happened right in front of me(!)...I couldn't get those duckbills out of my car fast enough! At the time, we were unsure of what had happened, but I knew in my mind that I wouldn't be happy unless I had a more secure arrangement in my car. Plus, I'm a 30 year FedEx employee and I've been our cockpits enough to know we use cam locks for all air crew members. I figure there must be a reason... 
Bottom line is you need to use what you feel comfortable with...it's your butt in there, and your skin on the line. One day they may find my lifeless body in the midst of the wreckage in the middle of a smoking hole in the ground, but they'll know where to find me, at least. 
Hope this helps...there's lotsa choices out there!
