HC Trade Uber Boss Killer Jugg Ideas

Hey! So I've been a long time casual player since open beta but would usually only play each league for a week or so, get to Shaper, and then call it quits. This league I decided to commit a little more time and finally got my first Uber Elder kill on HC Kalandra trade league with a RF Jugg! I was also lucky enough to be able to farm EoW invitations safely and made about 50 div + Ashes and Melding on hand.

Now I'm brainstorming more Jugg builds with these items that may be able to take on some Ubers. I have two builds in mind, a higher end HoAg and Summon Reaper. Here are some scuffed PoBs for my vision for them as a pure boss killer only build, no mapping considerations. If you've played similar builds, would love to hear general thoughts and which build archetype you'd pick. (Understanding that these PoBs are just templates and there are silly things like not meeting attribute reqs and not sustaining flasks completely):
