Sram 10-33 or 10-36? Your opinion is appreciated

I'm confused as to what options you are considering here, are you changing the chainring sizes or not.

With the 50/34 IMO either cassette would be fine. On a 50-34 I find an excessively tight spaced cassette is actually really really annoying because it causes me to somehow end up riding in a gear range where I have to make vastly more shifts on the front derailleur.

I have a bike with a 50/34 + 12-34 IIRC, the wider spacing gets rid of that dumb zone where tons of front derailleur shifts happen for me. Based on the 12-34 working, I would think either 10-33 or 10-36 would also not be annoying.

With the SRAM 48/35 setup for me at least personally I would definitely go with the tighter spaced 10-33.

I would also not sweat 65g if you're not a featherweight climbing specialist. Bike weight difference is going to be completely dwarfed by the benefits of getting the gear ratios right.
