Thanks to the authors
Bayani (arc 230100)
EvaDestruction (arc 161629)
for their arcs. We were on a small crew so both were a little more challenging than if we had a bigger team, but fun was had by all. And thanks for the continued submissions, we'll get to them!

So glad you guys enjoyed the Children of Astoria - Looking forward to your thoughts on the Legion of Mutants vs the Iron agents!
Glad it was a success!

Arc # 250142 Lockdown.
Specifically designed for teams. Difficult but not overwhelming. Many things are skippable (through stealth or avoidance) if pressed for time.
Custom villains and a storyline specifically designed to have a silver age feel.
Don't count your weasels before they pop dink!
Glory of Moment in my sig might be worth a look. It's a bit long (4 missions), but none of the missions are too big. There's plenty of challenge, even with me using only stock enemies! I mean, Malta... need I say more? Plus, Longbow Ballistas! (Ballistae? I can never tell.) There is a defeat all, but the map is quite linear and of reasonable size. And, yes I do have one ship... but honestly, it was the only thing I could think of that I use to transition to in case of both a failure and success. Give it a try. Could be up your SG's alley.
I have two arcs for level 40+:
#1152 - The Doctor Returns. This one has custom enemies and I haven't checked how I16 messed them up yet, so it might not be playable.
#281575 - Et In Arcadia Ego.
Winner of Players' Choice Best Villainous Arc 2010: Fear and Loathing on Striga; ID #350522
I'm thinking my arcs will fill the bill now. Fair warning, though they should meet all your requirements nicely, they're emotionally intense. Enjoy (I hope.)

"The Consequences of War" - Arcs # 227331 and 241496
I think you may have already played my arcs, MM (I flogged 'em pretty hard on Guardian channel for a while, after all, heh...), but if you haven't, they're in my sig- How to Survive a Robot Uprising may be a bit on the long side for your bunch (although I can promise a good story through it), but Small Fears should fit quite nicely.
Trollbane is a level 10-14 mission, but... well... i16 allows you to get exp while exemplared, so it's also an option 
(... although it may also be on the long side. Hmm.)

If you're still looking, I'd like to recommend my arc (from my sig) "Glory Days". Story based, mostly drama with touches of humor, and only one defeat-all (at the end, on a small bank map; all the maps are small or medium).
My characters at Virtueverse
Faces of the City
The Arc in my Sig might be of interest.
Should take about an hour (4 missions). One EB and a couple specific Bosses in the last mission. Good amount of Mezz and Psi type stuff though out. Mostly Custom Critters though with most on Standard-Custom/Hard-Custom. I look at still as a Work In Progress.
Thank you for the time...
@Travlr (Main) / @Tymers Realm (Test) 
My three arcs seem suitable enough and have got pretty good feedback. They'rein the 40-50 range and no Cargo Ships or Oranbega maps to my recollection
There's Web of Conspiracy (148880), Web of Conspiracy-Aftermath(185789) and The Fall of Rapture (299507).
Each are pretty save-the-world-ish but are apparently fun!
Check out the arcs in my sig ... hopefully you'll enjoy them!
There's both high and low level arcs, although ever since the new exemp. rules came into effect, even the low level arcs will earn XP on high level teams...
M.A. Arcs
Intended for high level play: The Primus Trilogy (Arc #s 10931, 283821, 283825), "Freakshow U" (Arc #189073), Purification (Arc #352381, Dev's Choice!
)Intended for low level play: "Learning the Ropes" (Arc #100304), "Cracking Skulls" (Arc #115935), "The Lazarus Project" (Arc #124906)
You could do worse than to give the first two listed in my sig a shot. =)
The first one, TOO MANY BUNNYGIRLS!! might be a tad easy (although the one chance I had to play it with a team it felt otherwise to me), although the last mish does have four placed bosses.
The second arc, A.E.'s Premium Quality Mission, should prove to be more of a challenge, but not due to any AVs or EBs; the custom group in the final mish is kinda tough.
Both are better for toons at higher levels (such as yours), are humorous in nature and sit currently at 4 stars with 107 and 52 plays, respectively. I hope you enjoy them if you do play!
I think the arc in my sig fits the bill quite well. It has it's challenging moments but it was created to be fun. I can think of some things it isn't, but "fun" sums it up quite well.
I'd also suggest anything by @Witch Engine, @minimalist, and @muu. All excellent authors.
If you're open to exemping now that exemping gives XP, then you might be interested in some of the arcs from my review thread. I've got the reviewed arcs listed in the first post, with links to the reviews.

I would say check out my Might Makes Right arc located in my sig. It's a relatively fast to complete action arc featuring the Malta, so you know you're in for a slight bit of a challenge.

Submit your MA arc for review & my arcs thread
I'd like to offer up my arc. It's best for teams and should offer a bit of a challenge. Apologies in advance for the first mission (ship) but it fits into the story.
