Bartok's Jocuri Poporale Romanesti is incredible. There's Oboe and Bassoon parts that can easily go to flute and bass clarinet / tenor sax. Same position, ZERO double reeds one Spring and this was so neat to work with students on. Will never forget that one!

We just did Red Rock Mountain. There's a short oboe duet that I rewrote to clarinets. None of the judges commented on that change and we got straight 1s.

Molly on The Shore
Holst Suite in Eb

Both pieces are written for smaller bands and have ALL of those parts cued all of the place. I have done both with zero double reeds many times successfully.
