Used the white Simms brush this morning. Seems the loft is fine for me giving decent backbone for a 3 band silvertip and soft tips with a slight bit of scritch/scub. The initial impression is quite good.
Turns out the brown one is a Simms too. You have to catch the light the right way to stand a chance of seeing the marking which is very hard to see. The brown Simms is next tomorrow.
