Awesome, thanks for the replies everyone!
I'll contact the fitter at CC and figure out if the D4 swingweight was based off the club he got fit with (and heavier grip plus fitting hosel adapter) or the recommendation of where the final club build should be.
On the club head weights, aren't those just screws (albeit Ping specific screws) that I could swap out to tinker with weight? Or, could I just add some tip weight to get to the right swingweight?
As I said, thanks for the replies so far, this is super helpful.
