| I reckon it's pretty much up to you and what you think you need and what gives you the "best" setup. When I got my Eclipse MR I had been playing a Schilke B1... another "open" horn. During the trial for the Schilke I had found that Warburton 4/B9 was the right setup for me... very "open". From there I went looking for a couple of minor intonation improvements and ended up on a GR 66***.... again quite open, especially with the GR backbore design. It works perfectly for my MR and I've not changed in almost three years now (briefly tried a 66** with a one-size tighter backbore and shallower cup but it didn't work at all for me... guess I just prefer "open").
You may not experience the same effects however! I'm only relating what I use and how I ended up there. I could probably improve my high register somewhat with a bit tighter backbore but I happen to like the intonation I'm getting right now and sound quality is more important to me than playing above 2nd ledger. |
