Without trying to resurrect the flame war, I have some interesting new information on this:
Dresser had a gig here on Sunday, he was going to use my speaker cabinet. Then the airline sent his Czech ease to Seattle so he need my bass too.
He sounded great on it and was doing all sorts of sub-harmonic and mulit-phonic sounds.
After the gig I asked him about getting a good bow turn when you do sub-harmonics, I can get a really good one with a down bow but have trouble keeping it going, which would make it more musically useful. He did it starting with short bows and then worked his way up, then handed my bass to me.
I was not warmed up at all, and on the first try I could do the bow changes with long bows, it is something I had worked on for years without success.
The Bass actually felt way more open than it had ever been.
It is way more responsive. I can now make phrases changing pitches with sub-harmonics now, and could not before - and I had certainly tried.
Here are some other responses I got from great, experienced bass players:

"your query is an interesting one. and i have some personal thoughts/preferences/theories about it.
1 - when i travel (especially by plane) long distances what i like to do is to play double stops with the bow on the 3 sets of adjacent strings:
1st = octaves
2nd = unisons
3rd = tritones
4th = minor 2nds
i play these slow and the dynamics: p, mp, mf, f, ff, then various crescendo combinations. i find the bass opens up from the travel in about 10 to 15 minutes of this process and begins to vibrate freely.
2 - when i'm home i always start with about 5 to 10 minutes of slow-bow long tones only on open strings. single strings, then double-stops (all open strings) at a dynamic of p. this seems to bring the body (my physical bod), the strings and the body of the bass into a nice vibrational space.
3 - i mix this routine up with pizzato on some days. when i do the pizzicato (after a few minutes of the above bowing routine) i work on sustain. will take an open string, pizz it and see how long i can hear the note sustain. then, i will proceed to different stopped single notes, pizz it and then see how long the note can sustain. i feel this opens up my ear/hearing sensitivity to creating a sustained pizz sound. it also develops the left hand's supple strength so that the note is not is not choked by the left hand, but held in such a way that the stopped note can sound and feel as resonant as an open string.
also, the perk in this exercise is the the right hand does not pull the string, but rather, it releases the string. this is important for resonant issues.
o just a note: i do this routine (#3) in all registers and in pizz and arco. and if i really want to drive myself crazy i will a tuner with a pitch indicator so i can see i can how my body effects the pitch (sharp or flat) of the notes as i produce them on the bass."

"funny question, YES! i am quiet sure specialy for wood instrument, more you play the same instrument, you talk with it, more you find your sound, your body sounds, it become a part of your expression, what you expect about your tool ; it's so personal an instrument..... so unique ( at least for me !!)
i am not a scientific specialist, it's also abstract, but this intimate part of you, this spiritual rare moment you have with your personal insturment, give you probably a kind of " osmose" with this wood instrument !!! it change the the " wood life""
