End Game Archer Build

So currently I'm at level 96 and my gear well is very under levelled and a mish mash of items, so my build is air and thunder with all skill points into those two elements. However I just looked at the item guide and the only real gear that suits my endgame build is siggattarrius and I can't see any other good gear for my build although there is a mythic bow called statiformis which is air damage. Anyone got any suggestions or should I try and new build ?

 

Only endgame bow I can think of that's air damage is Return to Ether. It kind of has a lowish base dmg but it might suit your build.
