#1...the faces of the eve figure and the P4 figure are the same...nothing was changed there. #2..Torino is THE joint expert around here....he spent alot of time trying to only change the Joint Parameters when working on eve...he finally saw nothing equalizing his requirements could be done and regrouped the figure. Tehre are some poses that the P4 will do better, but many more that eve well...and the collar/shoulder joint is oen of them!
