I bought them at the Redmond, WA Costco yesterday.
Have not had the chance to hit them yet.
Some basic specs:
52/10, 64* lie, D3 swing weight
56/10, 64* lie, D4 swing weight
60/8, 64* lie, D4 swing weight
Others are describing the grind as a "D" grind, and the shaft has a tough time keeping up with very fast swing speeds. Steel shaft, unbranded. Black grip described as "similar to tour velvet" branded as Kirkland Signature.
