Doesn't RR has some screen issue. It was mentioned in the OP of the ROM. I only saw that after downloading RR, so I didn't flashed it. Also, if you have tried any other ROMs too, suggest the one with best battery and no bugs. Thanks.
The last stable RR ROM for Lenovo A6000 Plus was "RR-N-v5.8.3-20170511-a6000-Official.zip" downloaded from here:
https://www.androidfilehost.com/?w=files&flid=120740
This was the last known stable ROM of RR (last known to me at least)
Features of the ROM that suited me best:
1. Very Good Battery - Full Charge to Full Empty - SOT = 4 hours, Standby = 1.5 days, Moderate to heavy usage using Camera, 4G always ON, Bluetooth Always ON and GPS also always ON, and with this usage it gave a full 21 hours.
2. Camera is very good in this ROM using CM camera which is way better than the MIUI Camera
3. Sound output from the speakers is awesome and loud enough; yet the sound is crystal clear and no crackling whatsoever
4. With JIO Sim set to Sim1 if I switch Data to Sim 2 then the Sim 1 remains Active unlike in MIUI the Sim 1 (Jio only) goes off the network therefore I am unable to receive messages from Sim 1 eg., OTP and other service messages
5. Multi-Tasking is a breeze
6. Minimal heating of the phone while playing games or watching videos
7. Sound output over Bluetooth Streaming is what I use while driving and its a pleasure to listen to music in the car while as on MIUI 8 its not so satisfying as all Channels do not play the right sounds on MIUI.
Battery drain is eminent same as MIUI however, I have noted that in RR the battery drains really fast till it reaches around 60% and then to 45% its very slow. Thats where I do about 5-6 hours of work before it drops again really fast to 35-38% and then from there to Full Flat another 5 hours.
I use my phone purely for Business so Emails and Calling is my daily work therefore RR is best for me especially the build of 11-05-2017.
In MIUI 8 I have noted that sound out from Ear-piece is very very low and I have to ask the caller to keep on repeating however with RR ROM the sound is very good and loud enough. Same with the Speaker Phone on MIUI 8 when I am listening to an IVR then I have to be in a near quiet zone else I can barely hear the IVR unlike in RR where the sound is LOUD !!
The later RR updates of Weekly and Nightly have several bugs and glitchy sound and video output with Battery drain and heating. However, the Dev is still working on a lot of the reported issues.
