yay someone stuck up for the FM's haha I'm currently running a delta 50 series in the stainless build and haven't had it long enough to say there's anything wrong with it at the moment. But in the future when I do (and I will eventually) swap out, I'll be going with an AT3030XL. I'm slowly getting tired of the 2k rpm drone it puts out on the highway now that I have 4.56 gears.

 

Ive got a single Delta 40 FM on mine. Although in this vid its half FM and half cutout..........LOL

And I dislike people that take youtube vids with all that wind in the background.
