You can't go wrong with this knot. Extremely soft, decent backbone, and great flow through. I just ordered another one.
The SynBad knot is the softest synthetic knot I've found to date. I have it lofted around 53mm and it has some backbone, but not enough to feel pokey when splayed. Great knot that looks nice in any handle it's set in.
Quality of the knot is amazing, highly recommended
Like the feel and how they look in the handle
