Got a question for you guys about metaltechs' A Arms.  The dude told me he can make any size a arm.  Extended 2" & 3" even.  Then he claimed he could build a plus 2 or 3 that would work with stock shocks.  My question is, if you make the a arms longer, does it create a lot of stress on everything.  In my mind, the more "extended" you go, the stronger the shock you will need.  I'm absolutely not going to relocate my upper a arm mounts to the top of the frame like a lot of people do.  I understand that by relocating the mounts to the top of the frame you can get a proper dune setup.  I just can't bring myself to chop on my frame.  Would +2 A arms with lets say an Ella stage five shock( of stock length)  be a good long travel setup that would be good for duning?  Or MUST I relocate the upper mounts?
