My understanding is that while knot diameter and loft are particular to each model, the actual bristles used are not. The only grading that Omega does on the bristles is whether they are good enough to use in their brushes. Several people have bought two of the same brush model at the same time and reported differences in the bristle. So you could have an Omega boar that you don't like, by another of the same model, and get one that you like. I've had good luck with the two Omegas that I own and would not hesitate a second to buy another.Which Omega?
I also like the backbone and scrub that Omegas are known for. YMMV
