Thanks Jeff,
And thanks for the terminology correction. Now I know it's not an unusual thing to ask for the radius to be altered.
I'll leave the main decisions to Lisa - she has a very good reputation, and has been very accomodating on the quick set-up stuff. Now that I have settled on strings and string-height, and the bass has settled in for over a year it's time for the full set-up and tuning to be done. That can be my Xmas present to the bass
