I bought the Vie Long horse hair brush. I'm not too keen on it. I've been going back to my TGN synthetic knots. I'll likely sell or trade the Vie Long so if anyone is interested, PM me & we'll figure something out.
I bought the 13061 and once I got rid of the chemically smell, it has been pretty good and better than my cheapo VDH. It hasn't shed a bit, and is breaking in nicely. I will be buying a badger soon, just to compare. Then I'll buy another brush....just to compare.
So far this is the most comprehensive site I've been able to find for Vie-Long brushes: http://www.giftsandcare.com/ They ship from the same place they are from (Valencia, Spain) so it seems logical. Not sure about prices but they look alright.
I think their badger brushes are their forte but some of the veterans here would be better at telling you that. It is pretty good for me because I can order from within Spain itself and get free postage but I am not sure if it would be worth it for you. There is a massive selection at the above site anyway so you work it out for yourself. Let us know how it goes...
