Can they do a 'straight-pull' headstock, flat, not slotted that's more LIKE an arrow-shape on a Flying V, but with a straighter string-pull, some extra thickness at the H/S (like a volute) and a wider-than-standard nut width for large hands?  Are the f'board radii standard or can we ask for specific levels of flatness?   I saw something that said 'All resonators are tricones' but this one looks like a reg. (sorta!) biscuit bridge and single pie plate...?  Finally (for Now anyway) can they do all of that in a LEFTY, and also a sieve coverplate?  Thanks.   -Al
