I already make my own, very similar but use the addis brushes, soft or hard, hard lasts along time and is very good for first cleans and facias, the soft can wear out in a fortnight.
They cost 3-25 each and are very light, although I still have a vikan on my 30ft pole, but only bcause I dont use it much and am waiting for it to wear out - maybe by the end of the century.
