Dang. Well if you are doing helis just do that line, and maybe buy a top tier premium if its on sale? You already know how to use APFSDS from your Macagh?
Maybe if you want it more on air wait for black friday and get the netz. I might get the Netz cuz I want the f-16, f-14, and f-15 but don't wanna grind america. Anyways, if you get tired of israel do USSR or germany. (Ussr its best to do arcade when you only have 2 tanks, because of how annoying the level 100 players can be, and less uptiers)
