5choffieldI know some people swear by FKS's but to me they seem heavy and flimsy - when they eject and the heel piece spins around
The heelpiece spinning around is completely by design... I'm not sure how you interpret this as them being flimsy?
Put it this way, I broke 3 pairs of Jesters in 2 season (every time the toepiece pylon attachment failed) and 2 of the people I ride with has broken them.
I then change to FKS, I've had 4 seasons on 2 pairs now and the only thing that has gone wrong is I broke the AFD off one.
SKInny_because of the way they spin and disengage your less likely to hurt your knees.
This is a complete myth, they are no safer (knee-wise) than anything else.
The pivoting is designed to protect your tibia.
