I know the common mindset of most around here seems to be that business and first class award redemptions are the best value based on high $/mile. For those of us with a limited number of miles (100K) that would prefer to stretch our miles into more trips by foregoing the business/first class cabins, what are some of the better values or personal favorites for partner awards to international destinations in economy class?

Central and S. America stick out with the 35K and 40K redemption levels.

Are there any stopover routes/open jaws that make for a good value combo trip?

Or maybe somewhere off the beaten path that is typically expensive to get to but takes a low number of miles for coach?

I appreciate any ideas or tips. Thanks!
