Straight-class single-target spell-casting builds?

Spell Sniper is mainly un-needed, but it is useful for ignoring cover/increasing Range, it doesnt necessarily add to damage directly, more a possible accuracy bump or allowing for mow attacks at long range.

Have you simmed a "Mailman Sorcerer" ? Basically heavy focus on Quicken + Twinned cantrips, Quickened Scorching Ray + Twinned Cantrips, etc. It requires a lot of micro'ing for Sorcerp points, and knowing which spell slots are the least important, so you can use them for extra SP. It also can be made more useful with Spell Sniper/Elemental Adept to make their damage/accuracy more consistent.

Can you work up a basic plan for the Mailman? Basically "at each level, what spell slots should I burn for SP?"

I've not done anything with quicken/twin really.
