Do you really need a STA if you are only diving with a single tank and the dive rite SS BP already has two slots for the tank straps? Seems like it would be fairly secure once the tank straps tighten the tank to the BP.
I'm not quite sure why a 2" crotch strap would be more comfortable than a 1".
As has been said, you can thread the cam straps directly through the BP. However, I'd give another vote to the STA! I find it much easier to assemble/disassemble my gear for cleaning as the bolts are held in place by the cam straps and you get butterfly/wing nuts to secure the wing in place.
