"I would save up more money and get rider friendly more versatile box."
OR you could do what I did and buy a dozen VR112 MkII's and love them every time you set them up. I have been doing regional festivals, symphony orchestras, local rock shows, and club gigs with 3 or 4 a side, for going on ten years. Yeah, I could have waited while I saved more money to buy some JBL or more "rider friendly" boxes and missed out on a few years of gigs so that some gear snob who works for the band could mix on my PA, but I'd rather mix myself, thanks. My clients like the fact that they can afford to hire me because I'm not trying to amortize a huge bank note, and I get to mix on one of the nicest sounding rigs I have heard, and I have heard them all, trust me.
Oh BTW, all the stuff you hear about "...can't curve them more than 2.5 degrees...?" is ignorant B.S. Yes, Peavey states that "...smoothest response is obtained at an angle of 2.5 degrees". So what? Every box on the market has angle that is "optimum" for that box. That doesn't mean that you can't use other angles and get excellent results if that is what is needed for the situation. Peavey made the mistake of confusing the masses by making the point that when you curve a line array you are fighting the physics that make them do what they do so well - control dispersion in the vertical plane and direct it forward. You are always better off doing near field coverage with (duh) near fields fills, and using the array to project at a distance.
So bottom line - if you want a "rider friendly" box so someone else will rent your rig and let you sit at FOH while they mix, get something else. But if you want a great sounding rig that one man can handle in a pinch, that sounds great on a wide variety of material, and that lets you buy about 2-3 times as many boxes for a given $$ (and don't forget, the real benefits of line arrays don't really show up till you get upwards of four a side, preferably more) then you should give serious consideration to a Versarray rig. And yes, they do have prediction software.
