I only use extreme brushes with extreme pole for every day use due to old injuries and new torn rotary cuff, it allows me to still work, but I've chopped cut and butchered more brushes than you could imagine to try make the perfect brush, I first changed the design of bristle on dual trim, by making bristle be dual all the way and for those that remember the bristles were higher at ends than now,
then spent years looking for lightest best brush and I still use my original prototype and basic lyyton it's like original extreme but with extra row of bristles and staggered down in three stages, and if I remember correctly I sent it to Alex and supreme was born from this brush it was the inspiration to the supreme,
I've frankinstined every brush possible but to this day the best out an out cleaning bristles I've used came from a old brush Alex did years ago simular to the tucker brush, but stock made it heavy but if it could be lightened and original bristles located in state it would be best brush for extreme range.
