Thanks Heavyarty.
Thing is the MH-60K kit contains all the parts from the "Night Raid" L kit, it's essentially the same kit from what I can tell having looked at the sprues in my box and pics of the "Night Raid" sprues, there might be a few extra boxes, bumps and lumps you can put on but the basic kit appears to be the same.
The G Pave Hawk kit appears to be the same kit again minus the long tubular nose radome and M60's (or SAW's they're one of the two) but plus the miniguns and ma deuces.
Both kits come with the squared off stab.
From everything I have read, and I've had that Aeroscale thread by yourself bookmarked for a long while now as well as this one - http://www.dishmodels.ru/gshow.htm?p=428, and looking at that build, although it's in 1/35 and he used the Academy kit, I should be able to build an L no matter which of the kits I have I use, so long as I have a second pair of miniguns for the windows (which I do) and an extra nose radome.
I'm guess I'll just have to start the build and see how it goes though, I'm sure I'm missing something from the kits OOB apart from decals and 1 set of miniguns...
