Well "Huge Choppas" or " 'Uge Choppas" are Big Choppas, its what they were called in previous years and Codexs.
Transports would be a must for such an elite based force, although it might not due so well with objective capturing with only 2 Troops. One possible addition to the army could be a unit of Grots to sit on a deployment zone objective constantly going to ground, although that would be your decision. (err I mean your friends decision).
How many Flash Gitz are in the squad, any idea? They probably have More Dakka (as 2 shots with Orky BS is always better than 1), although they may also have Shootier (which in my opinion it is a mistake to have more than 1 upgrade on a Gitz squad.)
Each troop squad comes to 410 points by my count (and not to bring up another thread, but that is with adding xx+yy for the Painboy). Which puts the entire army (bar the Flash Gitz as there is insufficient info to qualify the points for) at 1395, with a model count of 32 . Although that is assuming that the last listed Nob Mob is a clone of the Troops mobs + a Bosspole. If you add 3 basic trukks (and I mean naked trukks with no upgrades, not even Red Paint) your at 1500 even.
Depending on the size and the upgrades of the Gitz (assuming that there is no Kaptin) it could range from 180 points to 430 points, although that is if there is the Cybork upgrades. With such a low model count, and because of the abnormal abundance of Dokz, find out if there are any Grot Orderlies for FNP re-rolls, as that would help this elite force kickin (although it be at a price).
I think this would be an interesting force to see on the table, but not something to be incredibly scared of. Theres a lot of spice and flavor in this army, but no real meat and potatoes so to speak, and with so little backing it up, the army will crumble in the face of Dakka, particularly against Tau and maybe even the massed Lazguns of the Imp Guard.
Even against other Ork armies, this one might not have the staying power or the numbers to survive a few rounds against massed numbers of Lootas, SAGs, Kannons, Boomgunz and/or Kill Kannons. Although I do think that the army has a chance against other Elite based armies like Grey Knights, it certainly isn't an all commers list.
Granted thats just my opinion, take it or leave it.
