Can we get back to the original question? You have a gear ratio that you have been using for years. You want to know what you should change it to for next year?
But you know you are going to get sagged and that's fine. But you want a ratio that won't get you sagged? So it's not fine? Or that will get you sagged?
Is your goal to get as many miles as possible before sagging, or to get those miles as fast as possible before sagging?
Is there a training question here somewhere?

This summer a group of four of my friends rode from SF to LA fixed over four days along the coastline. They all rolled on a lower-70s gear inch ratio. I feel this talk of bringing an extra chainring/cog/chain is overkill and over thought.

The route closes in the late afternoon, and if you haven't yet made it to camp when the caboose comes along, you and your bike get transported to camp. So, yes; you do get sagged by the officials when the route closes.

Totally off the topic of gearing, but I've got a friend who does the AIDS Lifecycle ride every year, and I think it would be a great to try before too long.

i have a very big birthday coming up & plan to celebrate/thumb my nose at father time by riding fixed for a certain high mileage number up our coast highway on the east coast.
op, if you think you may need a bit wider variety of gearing, here's my own plan:
i have pretty long trackends & use a big chainring - going to throw a 17/21t dinglecog on one side & split the difference with a 19t cog on the other.
am figuring this set-up ought to enable me to handle just about any terrain. my calculations tell me it will fit my bike & chain, hope they are right...i'm not so good with this higher math stuff
whadaya think?

Or you can HTFU, stay w/46x16 and do switchbacks on the climbs. No shame in that game.
Btw, I did a metric century organized ride once on my fg w/some 18% climbs. Everyone else had rbs. Just did switchbacks and it was all good.

Yeah, I'd say the 15/19 set-up or the S3X would be your best choices. I have an S3X, and this type of riding is really when it shines. For example, I've only done city riding the past month, and haven't shifted even once (but then, I haven't gone into SF this month), and really don't feel a need to. But when I head out on hilly roads with mile-long grades outside urban areas, the extra gears do come in handy. Personally, I'm not a fan of flipping the wheel and adjusting the chain during rides, which is why I got the S3X when I knew I was moving to CA from the East Coast. If I'm gonna wimp out, it might as well be convenient...
