I wondered if the switch was perhaps subconciously echoing the changes in society since the first film (subconsciously because I'm doubtful JJ sat down and planned deep insightful sociological issues into his film!)When the first film was released it was unusual enough for a man to feel and display emotion for a friend so openly; nowadays we are more open (almost surfeited) with permission and encouragment for men to express themselves and their feelings, even for other men. By switching to the Vulcan, supposedly emotionless, the shock value is regained.

Also, quite possibly, I am analysing an action flick beyond rationality! I did enjoy it though, and yes, it hit the slashy buttons :D Although Cumberbatch always does...

Have some owls on my profile pic - they popped up on Facebook from the Festival CEO this morning so you'll probably have seen them already, but I did think of your wols when I saw them and abducted them for my own!
