I would like to know what the differences are between the three different WNW Albatros kits...the DV, the DVa and the DVa (OAW). I know that there are differences in the supplied decal sheets, but what about the plastic? Can I freely use any one of the kits to make a specific variant, assuming that I use the correct included parts (and other decals, say from Pheon)? I've looked at the PDFs of the sprue maps and it appears that all of the kits have the same sprue trees included. Any help would be appreciated! Brian
