Deep goodseeing HAWKI Ks images complemented with g+z photometry provide acosteffective and similarly sensitive alternative to HST for deep weak lensingmeasurements of massive highredshift clusters. We propose such observations forthe nine z>0.7 clusters with the strongest SZ signal in the new 2,770 deg^2SPTpol Extended Cluster Survey, aiming to map their dark matter content andobtain accurate estimates of their true mass scale.
