“I’ve had about 5 days now of testing the leadpipes out and the clear favorite is the 525CY. It’s a longer pipe that produces enhanced clarity in articulations and excellent feedback in the high register. Sometimes the sound can suffer with a tighter pipe, but I did not find that to be the case. Perfect all around pipe for a Bach 36. It beat out the Edwards #2 pipe I was currently using. The 525BY is shorter and feels more open. Perhaps on a different horn it would be great, but for my needs the feedback on the chops and ease of articulations wasn’t like the 525CY.”
