it's a toss up between unremarkable bones and nothing manacles. I like exotics that are useful nearly all the time so the boots would be great given that I'll have three jumps but with the height and control of the "balanced jump" perk. and the Nothing Manacles I could see as being a crowd favorite if you go voidwalker everything is giving you a shield your granade/melee/super; for me that is icing. I go fireborn mainly for survivability, with the shield and respawn but if voidwalker got a shield mechanic that would make me look at voidwalker more often.
