I don't have a valk yet and I was actually thinking of owning only one Macross figure since I really collect Optimus Primes. I researched thoroughly and rewatched the SDF Macross Saga and I thought that the best valk to own if you'll only be gunning for one would be Yamato's 1/48 VF-1S Roy Fokker (either the regular of the weathered edition) with Super and Strike Parts. Along with Hikky's VF-1J, this is the most iconic of the series which, even after Fokker's death, saw action all throughout. I was actually about to buy one until I saw the upcoming 1/60 V2 with FAST Packs included. The FAST packs for the 1/48 are hard to come by lately in my country, then after watching Macross Frontier and looking at the 1/60 Bandai VF-25's, I've decided to go with the 1/60 V2's
Hehe so to answer the poll, you want only one figure? Go for the 1/48 VF-1S Fokker with FAST Packs. Want to collect valks? Go for the new 1/60 line. It's cheaper and goes in scale with many other valk figures.
