What do you guys think of the three brushes? They all use same 24mm synthetic Maggard knot set about 19mm deep. I was playing with the shapes to see what is the right size and comfortable in hand. Any suggestions or thoughts on a proper size/weight of the brush or the knot selection? I was being cheap and bought the synthetic knots. I want to dip into silvertip but TGN has like 6 different kinds of silvertip and I can't decide. And also having the same description for Super Silvertip and Silvertip Grade A isn't helping much.
