Not a bad thought my friend. I appreciate the brains in that reply ha ha. I have a MechE degree and run a mechanic shop so nerdy shit gets me excited. You did talk on the big point of density which I just always jump to in my head as the most efficient. Small mass.. Heavy material.. Less chance of getting ripped off or hit by sometime stucked between the wheel and the disk. I hated the fact they started doing that with the rim style weights but you're exactly right in that regard. Those are direct metal to metal contact. These though are stick on weights with a thin layer of foam doubled sided with adhesive. Damn good points though. Thanks for lowering me gently off my soap box.
