If i were you id go with what people who actually use the stuff recomend... if somone has driven 8 years with AlterK and they arent faliure prone... then id go with that.. just be sure to grease it regularly.. find some seals for the heims.. and be really anal about making sure the steering linkage is tight... and check it whenever you do work to the car....
