The band I play for (First Section) played this in a set test piece competition in Wales at the end of last year. Most of us (I think!) found it a very enjoyable piece, not only to play but also to work on. We did, however, find it rather difficult in places to say the least!!
Forrest of Dean was a 1st section North West Area test piece a few years back - I did enjoy playing this on Horn and would class this piece on the difficult side - powerful and technically challenging - I'd recommend some extra top register practice for your horns - top C# and Ds.
