As far as a true single point goes, I've been very impressed with my CSM Gear single point - Doc's a Navy Corpsman attached to USMC Force Reconnaisance in Camp Pendleton - and besides the obvious medical stuff, he's also one of their assaulter instructors, so he knows gear, and makes some of the best stuff out there and is quick to ship, as well as putting your order to the front of the line if you're about to deploy - that's very nice.
I've also been playing with the Blue Force Vicker's sling lately, and it's growing on me the more I use it.
I think either would be a good aquisition.
