49.4 DE/hour on MP7 http://youtu.be/EutKiX-nW2E (720p video)
49.11 DE/hour on MP7 http://youtu.be/bDKMn7qt9C0 (older, lower quality video but with more potential, because of bad luck the score ended lower)
Templar should be used and here's the build used on both videos.http://eu.battle.net/d3/en/calculator/monk#aceYkS!cbd!YZacaY
You can browse for more older videos on MP5-MP7 and couple MP10 ones too with different testing results and details are found on the thread linked below.
Scores are based on the rules of this challenge.http://us.battle.net/d3/en/forum/topic/8568378716
Another option is the following build if you have problems with RD. It's close to the same performance.http://eu.battle.net/d3/en/calculator/monk#aceYkS!Zbd!YZbcaY
Templar isn't as important for this build so you can use Scoundrel if you want to instead.
The lower the MP, the better Fleet Footed becomes compared to Chant of Resonance. But Fleet Footed is also better if you're spamming the lower spirit cost Empowered wave. Even with WoL it can be better on lower MPs.
These are high LS Skorn/Doom Hammer TR/Bell builds for MP5-MP7. MP8 is doable but not recommended. If you want to go MP9 or MP10 then DW builds are better.
In the end it comes down to personal preference and testing with your dps and spirit regen amount to determine what's the best build and MP level for you.
