I can see your point for Snake, I'm saying in general a more popular nude type would increase it's loose parts value, possibly driving down the loose parts price for other items in the set.
When HT had it's pre True Type nude, it sold for about 12-15 dollars, no one wanted them back then, the cost of the other gear in the set drove up accordingly when parted out. You could say the poorly received nudes from ACE and Toy Soldier also impacted their boxed set sales too ( as well as dealer willingness to part out those sets)
If SST makes better headsculpts and has a better core nude, the sets are more versatile period. For consumers, for dealers to potentially part out. That's the observation that I'm making.
