Am trying an ultimate now Dazmond. Dupont, dual trim. Outer is flocked like i use with a superlite & i always like dual trim. Can’t say i’m overly impressed. It’s lightweight yes but the bristles are short & so the stock catches on hinges & trickle vents & just about everything else! Some of these trickle vents are so deep these days. And I’m not one to just go up to them & have a dirty frame above. I go over them. I’d rather put up with the odd run. Not the ultimate brush for me personally.I put my extreme from super max on my slx last week to test. Found it very light but needs a lot of action to clean compare to a super lite. Was gonna try a supreme but they’re only 23 cm long i think whereas i’m mainly always using a 26cm brush .
