Just to resurrect my original thread, I ended up buying two bows - one French and one German - to experiment.
First of all, I got a German bow from Thomann, their [url="http://www.thomann.de/gb/thomann_bassbogen_3_4.htm"]self branded [/url] one.
I followed this up with a French bow from Yita Music on eBay, a AAA Ironwood bow with black hair.
I also picked up a very nice [url="http://www.thomann.de/gb/concord_bassbogen_etui_2.htm"]case[/url] from Thomann to keep them both in.
When I started this thread I mentioned that I had been a cellist in my youth, so getting back into bowing has been quite exciting. German bow was new to me, but I have really enjoyed playing that style. The power and emotion you can get from bowing really is quite something...
Anyway, I have been impressed by the quality of both bows. They're very well made, dead straight, are a reasonable weight (both around 135 gms), and draw really nicely.
Thanks again to everyone who contributed to this thread.
