How's it going everyone? I am in the midst of trying to decide on a precision blade balancer, and I am highly considering the Koll Rotor Pro Balancer. I have looked extensively, but have come up completely empty handed on finding anything related to how to use the Koll Rotor Pro. I found the instructions, but they leave something to be desired. There are no videos or 'How To' threads of any sort on the Koll. People rant and rave about this balancer, but I can't help but wonder how it has such extreme accuracy to warrant a cult like following. When looking at other balancers, such as the DU-BRO Tru-Spin Balancer or SkyRC iMax Balancer (which both incorporate some sort of bearing / precision mechanism), I start to look at how these devices work.
