Great and I hope they can help you out. If You speak with Nick let him know I sent you to him and maybe he will be able to help a bit more. Haha. I ordered my first two pairs of GG from him amd he does some unique set ups too, like Skoak.
Idk about pricing between the two but I would expect Skoak to be less even with a MTO fee but who knows. They are the only people/stores I deal with anymore outside of bespoke guys due to the service and knowledge being beyond reproach.
