That's your answer to everything... You sell tall left shoes for a day job?
Does oodles of stock in "ACME Mismatched Footwear" get me busted?
Seriously.... nobody has a clue here on things SG.
1 - the SG has a thin mahogany neck, 24.75 scale
2 - the SG has a LIGHT 1-5/8 thick body that is relatively small, and has a decent amount of wood removed for control route and pickup routes
The W SG has an 1.75inch body - similar routes, but its a heavier body. However, the neck is also a tad longer.
What this all boils down to is what wood are you using. That is going to determine the balance of the whole affair. The SG is NOT neck heavy so much as players are used to an ass heavy guitar. Knowing that, though, the reason the L6s has a snakehead headstock is to remove a few ounces of wood weight from it, helping with the balance of things.
I dont think a 1.75 inch thick W SG will have any balance issues. The 1.675 thickness option MAY if you use a really light body and really heavy thick neck.
