Crankset recommendations - light, low gearing, powermeter?

[eljamoquio]

Today I sheared the left crank off of my crankset, and will need to replace.

I have competing needs, but I guess I'm looking for a recommendation for:

• a double
• that hopefully can do lower than 33 teeth on the inner chainring - not a hard-and-fast requirement, but would be useful as I go up some steep (20%+ peak grades) hills.
• that is on the lighter side if possible, as I'm apparently a weightweenie.
• ...and if possible, I'd like it to have a power capability for both legs (sum of both legs is fine, one leg doubled is not).

Back when I was actually purchasing cranksets and was knowledgeable about them, your choices were 130BCD and 110BCD. Now... ...there appears to be far too many options for me to quickly figure out what would best work.

Recommendations are appreciated!
