The Raphaels are an excellent choice for two reasons :
the quality of the hair is the same as W&N 7
you get more brush for your money since they are cheaper than the W&N 7 and a typical Raphael #0 is the same as a W&N #1 in terms of size
the real difference between these two is the snap of the brush is a little bit different with the W&N being more rigid and thus better for freehand painting small designs
I also do have Da Vinci, Escoda, Rosemoary brushes.. I think I have now well over 40-50 brushes.
I am stocking since I know that one day, they will get much more expensive than they are now.
I have only retire one or two Kolinsky brushes in my last 5 years of acrylic painting
