Totally working from Klacheese Survival build, but modifying to the PS world.  Will do a NM build next to see what's up.

Overall Rating:  B

7 chests, fast waves, low mob count, good pets and Acc  

This week it is the map of the week, so could be worth running it for pets and some side armor.  The double drops helps, but still the mob count per wave is Very low, like 600 on wave 35 and less than that all the previous waves.  Each wave is sort of 2 phases, regular mobs and then super wyverns.  

North BB is 5 DU long.

Party: 1 TB monk on North stack, 3 Summoners with guardian pets (monk/huntress), 2 South Stack, 1 North stack.

Alt Party, might get away with 4 Summoners actually, because of the number of towers.  After full upgrades.  I didn't try, but could work.

Flash heal as needed on the South, maybe every few waves.  But the South is very tight and never takes hits, and controls that whole end.  .

Minions are optional, but even just these few makes a good impact on the tighness of the build. The Ogre does a good job as bait to aggro the Super Wyverns that direction.

Hint 5: TB monk stands here.

Hardest part of this build is getting upgrades on the towers on Wave 1.  The South REALLY benefits from 2 summoners, so you end up with an upper running around and a TB at the North (but North really wants a summoner booster too), so first wave can be tricky.  If an adept can get both stacks SOME upgrades, that's better than none.  Keeping an upper in on wave 2 can be a pain, so I suaully switch them out and start upgrtading with the TB.  If you find something thart works well, more power to you.
