Ok, there are so many options and I've been doing as much research as possible, and now I think I'm ready to start auditioning bows. I mainly play tango and jazz, so my unmarked bow has been sufficient. Now I'm working on a lot more classical music and have a few unresolved questions before I finally decide on a bow. I know the main answer is 'whatever feels comfortable and sounds right for my bass.' What price range should I be looking in? I've heard that one should spend about 1/4 of the amount paid for the bass. Does this seem right? Also, do the 'upgrades' effect the performance or are they merely ornamentaion? For example, silver mountings and ivory frogs.
