I have installed one of the BLF rivets on my 10 wing for AOA. However, it is the Garmin/Dynon style that only gets one input with variable exposure (angle of entrance to port limits or restriction to airflow based upon the angle to the relative wind) to the relative wind based upon wing angle of attack. This has worked so well on the 12 that Van's has a bulletin and kit for setting it up.
I will report results in the Spring once flying.
Not sure if this would work with the two static ports stlye of AOA. I am guessing it would as flat static ports don't seem to be too different from the BLF style from what I have read. Also, the concept is differential, so as long as both are the same it shouldn't matter.
