thank you all for chiming in. your input is appreciated!
@ greitzer: indeed, i wish i could try every string in the book but the wallet, o the wallet

@ chris conte: yes those victory basses are, imho, the best! but this forum is not really for this discussion

that said i went through so many basses (fenders, g&l, rickenbacker etc) until i found the victory about fifteen years ago and haven't looked back since. i wish i had the money to experiment with uprights until i found THE one.
@bobby: a bass with 43.5 inch scale? good god almighty! what's the size of the bass, head to toe?
@ greitzer, chris and bobby: i think i'm going to stick with the dominants until they give their last breath precisely b/c they are stiff and will get my left hand (i am right handed) the proper "work out" and will turn the skin of my right hands index and ring finger into leather

once they're done i may post again and look for local l.a. people who have either corelli, superflexibles or obligatos on their basses and see of i can give it a whirl. nothing beats a hands on experience.
i have one more question though: what period is reffered to by modern jazz sound? is everyting before that old school? i love miroslav vituous, charlie haden and mark dresser's tone. obviously the string is just a part of the equation.
