If you like speed and rokkits I'm ont sure why you didn't go for Kult of speed?
Anyway your off on your points for your boss by about 20 points. I would drop the mega blasta and the frag stikbombz from the boss and maybe give the NObs some gear.

Your also short on points for your flash gits. I personally would put a NOb with each squad.

Without the basilisk indirect fire the standard Leman russ I think would be a better choice.

Sorry about the Kustome Mega-blasta I must have skipped over that part when I was reading the Bad moons entry. The only reason I said put a NOb with the Flash gits was to get an extra Rokkit or Big shoota in the squad. Since they are a shooting squad I wouldn't spend the points for a PK either.
I would say give the boss back his choppa so you can use all those attacks when he charges in with his nobs then if anything survices give them the PK.

I don't know if you have the points but stikkbomb chuckas on all the trukks would be good. It's fun to tank shock people with a little truck.

If you had 1500 points I would say get a battle wagon with 5 bolt on big shootas. Your reasons for this army are all good and valid so I hope you have fun and see how this list does.
