String Spacing at the Bridge..

[Pino Cazzaniga]

Usually I let more space at G side than at E side, string to edge of fingerboards.
Some clients prefer that part of the fingerboard flatter (crossway) to give a "platform" to the thumb.
If you prefer close string spacing and high arch this is not advisable, as it can result in buzzing low positions when you dig.
I can't say about beveled ones, here they are a rarity.
