Hello guys, this is my first post on photography-on-the.net forum 
I'm from Italy and I'm a young professional photographer (28yo).
So I'm totally new to this forum, but I've found many useful information here, so I've decided to give my contribution.
I own a 7d and a 5d mark I, and I'm using Phottix Strato II actually to trigger my 2 flashes, Metz 50 AF-1.
So I've decided to upgrade my triggers with e-ttl model and, the most interesting feature to me, the FP or HSS.
Next year (i think on April) I'll buy Phottix Odin for sure, I think its the best and reliable wireless triggering solution.
But for now I've choosen the YN 622 
I've ordered them yesterday, I think the will be delivered on Thuesday or Wednesday.
So I'll let you know about Metz 50 AF-1 compatibility, hoping this would help any other users using these flashes.
