i used to have AGX's. I was happy with them, but they werent enough for the skunks i used to run. the one thing that i noticed about them though, was for adjustable shocks, there wasnt much of a difference from hard to soft. Maybe it was cuz the skunks were too stiff for them, but with the tanabes i have now, theres a noticable difference from each setting, with the AGX's, not so much.
Though Eibachs are gonna be softer then skunks, so you should be fine.
