I use a baroque bow and find it is much quicker, but I do not get the volume and power as I would with a modern bow..that I need in the bottom register of the violin. It can be achieved through conscience effort concerning technique and practice.Switching from the modern bow to the baroque bow was not difficult and I even play my "modern baroque" in the authentic fashion: i.e. no chinrest or shoulder-rest devices and sometimes the instrument is held down at the breast.( a practie I adopted long ago due to both physical demands and playing in groups for many hours at a time) The only deviation from authentic practice that I do is use metal strings,as plain gut are not only insanly expensive, but not viable for everyday economic purposes. Plain Gut does not wear well and in my opinion, should really only be utilized on a quality Baroque violin in keeping with authentic practice. Spend the money where it will do the most good. The overall feel is different, since the baroque bow is shorter (mine is snakewood and is 695mm in length and ca.51g in weight.) Another possible choice would naturally be the Baroque viola bows, which range from around 715-720mm and 56g. With baroque bows, lengths and weights vary. Then there are the "early classical" bows, such as Tartini or Mozart would have used, that are more in line with the specifications of the modern Tourte bow.But the transition then was not instant even then.
There are many good bargains available online, but beware of overpricing..I purchased mine from a certain popular auction site for under $100.00 and was very satisfied, as well as surprised, with the quality. Remember, the bow is the soul of any string instrument. Every player knows what works for them, no matter what the norm may be at the time.Improvements in any design requires experimentation, but not all improvements are necessarly progressive.

Count me in as another convert to the baroque bow. Not all of them work as well as others and I think should be tried before purchased however. Mine is a very stiff snakewood (with black hair as well) that responds perfectly with my setup.
