I bought my first GH off the rack at Surfy Surfy from JP in like 2013, I wanna say. Found him on instagram @surfysurfy upon moving back to North County last year - wanting to get a new board, etc... He was super responsive and helpful, FWIW - I'm sure you could hit him up on IG.Love Gary's shapes; his bonzers would be a good good-wave board as the three I've had all had some significant flip in the nose. Made groveling kind of a bear but when it turned on, it was great. Had a magic 7'6" I sold to @Bryce whose father enjoyed it for a long while after me.
Slingerland might also be a good resource as well, reasonable last I checked and his shapes are excellent, foiled, can't-go-wrong kind of boards. Not sure how to contact him now because of the Surfy Surfy closure but I'm sure JP St. Pierre could help connect you, or Jon Peck at Christenson/Moonlight since most of Mike's boards were going through Moonlight or Global Glassing.
