As for comparing my older smaller-bell Blackburn Eb with the larger-bell Pfund Eb with a C bell, these horns are both great for solo work. In general, though, I prefer the larger bell Eb as it sounds more like a C trumpet to make certain passages in the orchestra or chamber orchestra work more easily.
As for piccolos, I played a Yamaha Custom three-valve which is a wonderful instrument with a great sound. I now use Bill's pic (similar to a Schilke) with a cornet style mouthpiece. I find this set up a little easier in the upper register and more helpful with endurance.
My Pfund horns are weathering well. The horns still look good. I do take care of them and keep them clean.
As for my rotary C, I have grown to favor this instrument in the chamber orchestra and playing with the First Presbyterian Church Worship Brass (Colorado Springs, CO). The rotary is easier to play and has a nice warm blending sound, while projecting into the sanctuary very well. I've also used the rotary C on Lincoln Portrait in an orchestra setting with success.
In general, Bill's horns are working well. I enjoy the flexibility of tone color they allow and the ease of the upper register. So far so good!
