Epek ID

[TheSwede]

Can someone help me ID these Epek broadheads. I know they have had a few different generations and improvements on each one. Of if you can tell me where to look to figure it out. Thanks.
I got them in Feb/Mar 2011 thrown in with a used bow I bought.

Look like 2nd gen to me. Shorter beefier shank.

Thanks for the reply. I posted a pic on Epek facebook page and that was the reply I got as well. 2nd Gen for sure. Still on the fence about using them this year.
