some sth 12s do NOT have the driver toe, and that makes a huuuge difference in retention. Also, generally speaking, you do not want to be with in 2 din settings of the high and low end of the binding settings.
IE if you ride at a 7, the griffons would be better b/c you would be in the middle of the din range vs being 1 above the min on a Jester. Being too low and too high can lead to release issues.
