Spider-Man's suit isn't as intricate as Batman's so if they use very thin rubber, it could be a possible choice. Medicom's SM2 cloth version is horrendous compared to the SM3 version, so unless they can pull it off, I think they'll use a rubbery material.
Off topic, ShaDoWz I love your 09 movie ratings
Any word when to expect this line 09 or 10?
