I would go with the greassable one's. They are Poly to start with which is MUCH better than stock OME rubber. Keep them greased and you will never need to replace them. Keep in mind the Poly is harder than the rubber, you will feel more out of them, but they help tighten up the front end a tiny bit too. The rubber will become brittle over time, or like mine did, smash over to one side and then allow the crush pin to move back & fourth.
