Mayhem in Manila probably deserves to be labeled the first DASL "classic" scenario. It has it all in spades for DASL.
I've personally enjoyed FE's "Aux Barricades"; HoW9 "A Perfect Match" both are extremely good and well balanced - and the unbalanced but fun to play DASL A13 "The Mailed Fist".
DASL is more popular since its inception than most ASL players realize, but it's been ASL's "Dirty Little Secret" - and ignored more often than not.
There is an older GS thread ( pre- LFT's Deluxe Pack) that listed all known DALS scens I made once. But you can see them all in ASL Scen Archive, just do a search with the "Deluxe" switch set to "Yes".
For Dennis and I, DASL is a "go to" for VASL games. We're far from finishing even half of the ones ever published.
