I have been using the R7 quad TP 400cc. for two years and have it set up with 14 and 12 in toe and 2's in heel. Go online at Taylormade and check out their wheel or buy a wheel, this will set you up as you desire. On TM site, using the wheel is fun so I just bought a wheel for 12 bucks and I change my weights to accomodate the kind of course I play. You just can't change the weights during play-against the USGA rules.
Beats lead tape which is what lots of us used for many years to get the shot shape we wanted. You will see some pro's today still using lead tape.
