I set a 24mm gelousy fan knot in a handle I have as a test run. I didn’t pay attention to the loft height or anything like that. Just siliconed the handle and threw it in. The knot has some serious gel tips and the tips hold a lot of water. It’s unbelievably soft. I think the current configuration of the handle that I have is drilled at 15mm and it’s pretty floppy. I like it but it could probably be set a little lower. Lost about 3 hairs on the first shave so normal shedding for a first use. I’m probably going to order more for my other brush handles. I didn’t find the knot as dense as the Maggards SHD. Here’s a pic of the knot after the shave during the dry down.
