I would say that you will need the superlite stiff , when i changed from vikan to gardiner i went to the superlite medium mixed , great brush but i found it went out of shape too fast for my liking , hence the swap to the stiff version , these last very well indeed , having said that , they can be harsh on lead and small pane windows , they can also leave bristle marks on the glass if first clean or builder clean .
I now use extreme stiff only , as i only do repeat monthly .
My advice would be to get superlite in stiff and medium mixed , chop and change them according to the work in hand , this will give you the insight into bristle types while also halfing the weight on the end of the pole
I cant as yet comment on hybrid or supreme stuff as have not yet used them , but i will soon im sure
Dazmond or Number 23 will be along shortly , now these pair have serious fetishes with the weapon of choice , you my friend have only yourself to blame
