I Traded in my perfectly weighted Elyte driver for the new Quantum Max. You can not buy assorted back weights for the driver to get proper swing weights. Callaway does not offer them. They suggested LEAD TAPE on my brand new driver. Now I have no driver since I traded my Elyte and no way to balance this new piece of S.. t without LEAD TAPE how high tech of callaway. Extremely pissed and out 2 very expensive drivers. Guess I’ll load it up with LEAD TAPE and send pictures of Callaways new swing weight technology. LEAD TAPE
