I've been suspicious of my son's new driver since he bought it.Yes off of eBay. He hits it far (animal) but can't really control it.We were adjusting the back counterweight and checking the swing weight.For some reason I checked the counter balance weight and it read 2 grams.But checked it on my scale and it weighed 6 grams. My question is,if the head is counterfeit,would the counterweights be fake also?
