Andrew46,
I have superlight brushes on all my poles, I have all the three diffrent types of superlights,some mark 1 superlight brushes and some mark 2 model.
I think the duel trim brushs are the best but to be honest theirs not a lot in it. I have single trim on some poles, Duel trim on a few and I have only one flocked duel trim which I did not like at all when I first got it, Tried the flocked on my 17'xtel but the extra weight of the flocked made the pole a bit more bendy.
I put the flocked brush on my 18'slx about 4 weeks ago and its a superb combination,I love it.
I have tried most other brushes,some have thier plus points but to be honest at the momment use the superlights theirs not much to compare with them, they have good scrubing power combined with low weight which is the holy grail for wfp.
My son had the fiat doblo,I have posted photos of the set upon here,I had the tank frame made up but a mate bought it from us a couple of years ago.
