I searched the BF forums for a thread about this topic (using the word: Polycarbonate ) and could not turn up a thread. So here it goes. Metallic body material ( some kind of mag alloy, or aluminum) vs plastic (Polycarbonate & whatever it is Zeiss uses in their FL line). I understand the virtue of the plastic is lighter weight, all other things being equal. But what is the virtue(s) of the metals?
Does the body material relate in anyway to alignment/holding alignment, or in any way to general durability?
I own several pairs of porros that are polycarbonate and they seem strong, but I havn't put them through any sort of abuse and they cost less than $300 US new. I don't think I would pay 7 times as much for alphas made of plastic.

I have some car bins, from Walmart, that cost me $9.99 and have a full metal body, so using metal probably isn't a cost issue.
My FL's, now rigerously used for over a year [with lots of bumps and a few small drops along the way] are like new and they still feel nice and light in the hand. They are rubber-covered anyway, so any tactile difference is all down to lightness.
