Interesting and new design. There are a couple issues I see with it. Personally I like the extra bungee tails that can be woven in to the strong side of the molle on a flak. The problem with something that bridges the front and back plates is it can override the quick release setups on the vests that are used to shed them when in water or if immediate access to a GSW or other injury is needed. Also, when you have the strap coming across the front of the flak lengthwise you cover up things like grenade pouches. This is one of the reasons 3 points are terrible, though this is less of an issue. I personally just patrolled with my 1 point thrown over my neck, some guys didn't use slings at all.
Interesting design, and everyone likes different kinds of gear, but I think the carabiner set-up is a little cumbersome.
