Here are some good .5s-1s that aren't on the list.

Midnight Suite - Balmages (Sky, Mission, and Madness) would be at the .5 level.

Joseph Compello wrote a piece called Antiquitus that's possibly a good one too.

Rocky Mountain Romp - Balmages

Pixels - Standridge - this is new, I did it with my non-varsity 1C group for our winter concert, kids really enjoyed it.

Castle in the Woods - Randy Navarre

Prehistoric Suite - Paul Jennings

Battle of the Primes -Patrick Roszell

Soaring Through Ionian Skies - RW Smith
