They probably did show up sooner on the west coast due to being close to the factory but they are in stores everywhere now, I bought some from MF two weeks ago and picked up another three packs at my l,ocal GC in Dallas Friday.
I love these strings, hope I can score a deal at the DIGF in April on a box.
The Charlotte Sam Ash does not have any, nor have they had any yet.
So I bought regular slinkys.
I imagine bringing a new product to market on what is likely a large production scale is quite an effort.
