    Poly mounts are really the way to go in my opinion from what I've learned

    Drilling drains the fluid which, if left in will eventually fail. Filling it with RTV makes it solid sort of like a polymount except without the excessive vibration and even the solids tend to have fluid in them mine were solid (supposidly) shook them and you could hear the fluid in them (I got them from Rock auto).
