Well that turned out not very short at all! If you'd rather just read this and look at the D3planners down below that's fine too! Timestamps if you want to skip to different builds. My Twitch Channel that I've been very regularly streaming on this season is / tubahero37
Note on the LoD Monk: I know Swamplands are a bit more damage, but I feel aren't worth the investment if you're not going to try taking the build into multiplayer. There's only a tiny window of time where they would be needed to make the build function on T16, before that you'd still be weak with the swamplands, after that you're so strong you don't need them, so I just don't bother for T16.
Adjust the GR farm levels up or down as your gear/mainstat levels change. I was doing low 90s with the barb build originally with some more defense from Superstition and more vit, and dropped as I gained more All Res and Armor from having higher Strength.
With regards to the two different bounty builds, if I'm running several acts of bounties I typically put on the tankier one and run all the bosses, then the faster one to run everything else. Similarly when I was doing split bounties on DH with people in the past I might take my impale and kill all the bosses, then multishot for all the other bounties.
These planners are not necessarily the rolls on gear that you should go for, but they're exactly what I'm wearing in this vid.

Recently I've also been doing some other monk GR farming. While I use the above monk build in 105s in a little under 3 minutes average still, I use this build to go 4 tiers higher about 30 seconds slower https://www.d3planner.com/257175191
And this one to go 4 tiers lower and about 30 seconds faster https://www.d3planner.com/640583857
Even more recently I RIPed my push Barb. In an effort to regear as fast as possible, I'm running the exact same Barb speed build on a very low tier (95s) but have also started farming keys/pools on the barb so I get more Barb drops.
