From just thinking of possible situations, a V is much more efficient especially in a medium-large commercial sites. However they weigh more and I don't want to hang that much weight off the front of my truck. I'll upgrade to a V when I get another truck that is a dedicated work truck.
And the commercial accounts I do can be done sufficiently with a straight blade. I've been told a straight is better for resis but I think a V would work great.
I notice you have a half ton, I'd really recommend upgrading before plowing. I see lots of half tons with plows on them and couldn't imagine plowing with them, there have been a couple times this year that I'm thankful for my 8.1 and I don't think the 6.0 would have the power to move some of the stuff I did and stack it.
