Okay, I'm not into name-dropping, but a chance encounter I had recently pertains to the discussion of Velvet bowability. I was at David Gage's shop getting some work done and John Patitucci happened to be there gettting some work done on his new road bass. After Mike Weatherly introduced us I hung out probably longer than I needed to, talking to John (very nice guy) and listening to him play the bass as Mike made adjustments to it. We talked very briefly about strings. John had EPs on his bass and I was reminded to ask Mike how he removed the grime that Velvet Blues left on my fingerboard. (The answer is a fine cloth or fine steel wool). John said something about not wanting to be anywhere near Velvet strings when he had a bow in his hand. Obviously that's just his own experience.
Me, I don't know, since I'm not going to start on the bow until I master two more Lennie Tristano/Sal Mosca-created exercises that are probably going to take me at least a couple months a piece. I love the pizzicato sound of the Blues on my bass, both acoustic and amplified.
Someone told me Animas bow better than Blues. I have a lightly used set of Animas in my drawer, just waiting in case that's true. I also still have an un-opened pack of EP Weichs in my drawer, just in case I wind up agreeing with JP.
A few things:
1 - Patitucci is one of my favorite all-time players.
2 - After about a whole year, my Velvets are much more bow-friendly, and I'm getting better bow sound than I ever did with Spiros.
3 - A few months ago, this guys from one of my country's major orchestras came by, bow-played and sounded great on my bass strung with Velvet Blues. Not as good as he would've sounded with, say, Flexocores, sure, but I'd settle for his bowed sound on Velvets any day.
4 - I still can't get really comfortable with Velvet's texture on my left hand fingertips, and I had to make some technique adjustments on my plucking hand too.
5 - I think next time I'll go the extra kilometre and get the Animas.
My $0.02.-

Doesn't stop me from trying to bow them though
