I've broke several heel bails on td 1s @td 2s.As your boot moves in the binding,you create friction.Sand from the parking lot in the heel lip,after time it makes a stress riser.Inspect your bindings often.I went FIN-TEC have had no probs.But I will replace my toe bails,as they have two seasons on them.Nothing is ment to last forever,Fin is getting real close though.Bring on that td race I got money to spend.:D
