Jim Keith says: "my opinion... they suck... kinda like the old alto and tenors on ebay with the fake nickel plating... just old and worn out and not any good" but has he actually tried one? Probably not! And exactly what are you referring to when you say old altos and tenors with fake nickel plating? Are you referring to the silver plated horns like the early Conns and Bueschers? Those are some of the best horns ever made, and most people couldn't wear one out in 2 lifetimes! The last thing we need here on saxquest is another kid mouthing off about something they know NOTHING about! I've used a couple Runyan pieces before. The older pieces were pretty good; the newer ones....I'm not so sure. I tried a Quantum Spoiler and it was just a little too much for me. The piece had a very raspy nasally sound on my 10M. I've found that sometimes the spoilers can cause intonation problems as well with certain horns. As you probably know if you've read my posts, I really like the Otto Link pieces; both their hard rubber pieces like the Tone Edge, and the metal Super Tone Master. I have a couple Meyer pieces also that I really like.
