I was taking a look at pics of 1/100 Toynami valks, and yes they're not perfect, but in that scale I don't think you can do a variable valk any better and keep it sturdy and playable. Lets face it, these are made to be handled, although not as much as any other toy like a transformer. Since they come fastpack ready, has anybody of you considered they were maybe GBP-1S ready also? That's why they have slimer lower legs and big shoulders. Look at Yamato 1/60 and 1/48 valks, for them to accomodate shoulder launchers you have to put additional shoulder pads. That's why 1/100 toynamis have bigger shoulders, to put shoulder launchers on them w/o other accessories. Since the major gripe on Toynami masterpieces was how flimsy the valks were, the legs are skinnier because of the leg armor for GBP-1S, you want to have a durable piece at 1/100 scale, that means thicker material.
