I had to replace the original Blue Mountain on an old cue - it was so nice and smooth. I don't have a pile of cues to compare to, but I wanted it like a Schon - about that amount of smooth.
I ordered a small spool of Atlas' current Blue Mountain, and a spool of their Hurlbert. After reading about how the new Blue Mountain just wasn't the same anymore, I had the cue wrapped with Hurlbert (double-pressed).
I don't know what Schon uses, but I wanted that same feel. I ended up wishing I'd wrapped with the BM, because the Hurlbert has just a little too much texture. Not much difference, but noticeable.
