Yeah, I was thinking the same about the Blue x....that could get tiring.
I spent time on the GC2 at work last nite with the g30 lst and the white tie. Hit it 283ish...average of 5 and hit it better turned up to 10 degrees.
The M2 odd the shelf is a bit longer so fitted should be different. I'll bring the Ping anyway. I hit the M1 and sometimes I get a loud hollow sound whereas the M2 always sounds solid.
One thing I found tosay at the store was I just don't put much spin on the ball. The M1 was better with the weight further back.
I put a HOF LD ultralight in the Ping last night...fun!
Hit 5 balls about 10 yards further with it.
