Thanks! Yes, that's a good idea!
Good idea too, but those sculpts are just too good to keep covered up!
Everything you said is spot on. The ROS Rey is indeed overall just a better made figure. But still, TFA Rey is iconic. The ROS Rey's outfit is not fragile, but only time can tell about the arms. I too am very leery of the rubber arms. Even switching out the hands was a little uncomfortable because as you hold the arm to put the hand in, the rubber slides down towards the wrist when you're applying force. Nothing bad happened, but it's weird and it could lead to something bad if you're not careful. For long term poses I will definitely be keeping her arms fairly straight, with maybe just the slightest bend to look natural.
I have all 3 Reys and can find something positive about all of them, so I won't be splitting up the group any time soon. But if I HAD to choose, then yeah, maybe I'd go with TFA Rey since it is the most iconic. It also has the 2 different looks you can give her: the full desert gear or the regular look. Plus she has BB8.
Good eye! That is indeed a trumpet mouthpiece! My F-I-L was cleaning out his basement and handed my wife and I a box of stuff he couldn't bear to throw away. Among that stuff was that trumpet mouthpiece (no trumpet!) which I immediately thought would be a good helmet stand! Kylo has a bunsen burner stand for his helmet, also courtesy of my F-I-L.
Thanks! Honestly I didn't do anything special, just smooshed the hood down with my fingers, maybe tugged downward a bit too. I'm surprised too that it ended up looking ok.
