I love big brushes and own several. I have also owned several Thaters. I didn't even know this brush existed until I saw it on Fendrihan's site yesterday. It is the Thater 4125/5 3-band and it has a 32mm knot! It's 124mm overall, but they didn't state the size of the loft or any other dimensions. It took me about 30 seconds to decide that I had to have it. In the pic it looks like the biggest bulb ever! If this monster has Thater's legendary soft tips, my Kent BLK12 is out of a job.
