That controller problem you are taking about is a problem of the RPM control. At 72V it is not possible to get the throttle at the right possition just a little over the rpm you are doing right now, so that the controller is not pushing to hard. So you are under your "ride" rpm and the motor does nothing or you are over your "ride"rpm and it is pushing fill throttle to reach the rpm you want with the throttle.
What you need is current control! then you don't tell the controller I want exactly 2000rpm, you tell it I wan't that amont of power, no matter what rpm you are doing. That is a really big difference!
The chinese bicycle industrie is starting to understand that, we are at a turning point right now. The new sine-wave Controllers can do current controll, thats the ones you want to go for!
The BBS-Controller can do current control to, so it won't have problems with that rpm control but there are several other breakdowns the controller has. The soft start is making the throttle-response really bad...
