If you're stuck on a single-point sling for a carbine, I say go with a Gear Sector A.S.P. For a two point...my personal preference for a carbine...I say go with a two-point like the Vickers VCAS. If you're holding your rifle and it's time to go hands-on, it's awfully nice to be able to pull the rifle close with a two-point sling.
I personally stick with single-points for SBRs and two-points for carbines for patrol use.
There's always the best of both worlds with a Magpul sling, the QD MS3 being a favorite for me right now.
