Put the AMS ammo in the head, or better yet, just replace it with 3 more jumpjets. That's what I'd call jumping instead of hopping a few feet into the air. 1 JJ is barely enough for very small hills, especially since your targetting is hampered while using the jumpjets, and only accurate when you are falling down.
It's just that I think you don't need the AMS so much. Since you can play as a poptart and/or put both PPCs in one arm, you can stay in a lot of cover most of the time. So if you remove AMS and keep that DHS you'll have the same 40%+ efficiency and much more JJs, while losing very little in terms of actual defense. You could even mount an XL300 for that weight like this: the extra speed is imo more useful than the AMS support.
