First - Heavy Earth was made from the Earth map, not the Medium Earth map. Why is Light Earth being made from the Medium Earth map?
Second - Both of your maps have 25 bonuses, which basically means you're just reshuffling the bonuses rather than increasing their size. Medium Earth has 23 bonuses + the 1-territory 0-bonuses. Earth also has 23 bonuses.
Third - if Heavy Earth is the opposite of Light Earth, then Light Earth should have bigger bonuses, but less bonuses overall. I'm not sure I like the idea.
Fourth - your bonuses seem to cut through countries - which doesn't seem quite right, as Earth/Medium Earth/Heavy Earth all follow those borders. Arun's worse off in this aspect but both have this in Russia, China and Mexico.
With that being said I think I would prefer Arun's option slightly more but neither of them seem great. I might put one up myself.
Although, a "Light Earth" would benefit a lot from moving of territories/added connections... Antarctica's awkward because it doesn't function well alone and it doesn't combine very well with other territories.
Assuming you want a map with bigger bonuses, less bonuses, and on Earth (not Medium Earth), well... http://warlight.net/SinglePlayer?TemplateID=451360
would be my idea. Territories marked AN(0) should be combined with neighboring territories. It has 12 bonuses, much less than 23.
