Woo never used three brushes for one shave before! This was a fun, I enjoyed being able to do a side by side comparison of bleached vs natural, I thought I liked unbleached knots before this and it's nice to confirm this belief. They're pretty similar but the bleached knot has less backbone and maybe a wee softer on the tips. The density of both the 80's gives for a real nice flow though of lather and nice massaging of the face, great brushes and even better for the cost. The 506U XSE felt like I thought the omega would plus the knot felt denser then the 80's and just ate up soap, the first two times I thought I had enough lather it just pushed it deeper into the knot and I had to load even more soap a real lather hog, real reluctant to part which the lather. This knot almost feels too low lofted for how dense it is but I feel like this knot after a year of shaving the hairs would split longer and maybe open the knot up more a make for a divine brush.
