Agreed. I'm still happy with the 64 and 60 degree wedges from the level 70's and never seen any reason to upgrade.
I did get sucked into the MacDaddy 100 yard wedge, which I am also happy with. The only difference between that and Cleveland counterpart is more forgiveness … which I can use.
Once one gets locked into the 60-80-100 yard sequence, and with the Cleveland 64 degree wedge which works from 5-60 yards pitching, punching and full shots … there is no reason to change.
