I hate to say it, but why not silicone? Hulk doesn't have any accessories or even detailed costumes that need engineering, so why not plug some of that R&D money into a high grade substance that won't deteriorate or tear and will do away with joints? It'd be a good way to test the waters and see what all of the pro-plastic joints people would think. I'd just like to hear your thoughts. Would you guys be so against a seamless body if you knew that it would not deteriorate, tear, or hinder articulation? It's a very interesting topic to debate.
But silicone isn't rubber, it's a durable, high-quality material used in special effects. It also yields some incredibly realistic results. Personally, I just want to hear people's legitimate thoughts, as, if I get any Hulk, it'll be a 1/4 Hulk, anyway, but it seems like some people are too closed-minded to even consider the possibilities.
Be that as it may, he would still suffer from "noodle arms"
when you move your arms, legs, whatever, muscles flex and bulge under the skin, causing it to stretch in certain ways.
The joints on those seamless figures don't have plates and things under the material that cause them to flex properly. this causes the material, instead, to bunch up at the joints. and ends up creating a LESS lifelike appearance than one that simply has exposed joints.
In essence, It effectively creates an uncanny valley effect.

additionally, the R&D in hulk , instead of going to accessories, is already going towards his body. As it stands right now, using a body type similar to Jake from Avatar, he is going to be in the 250-350$ range, possibly more.
Considering those Phicen Silicon bodies are 100$ BY THEMSELVES, the RnD costs going into a WHOLE new process? we would be looking at a 500-600$ hulk Figure.
I'd be very interested to see one of those bodies put in some "hulk-like" poses, and see how close it can approximate them. But in the end, I think, as he's an action figure, I'd rather just have exposed joints for better articulation overall, as well as having him fit in with the rest. I have GI joe toys in display, I can have BIG action figures on display too
