i have a constructor brush, no not used it in the winter so sorry can't answer your question but i cant see why it would not operate as good as any other brush on the market, time will tell.
It is a bit weighty and i do tend to revert back to other brushes now and then, especially if the pole will be fully extended over a conny or extension for instance but i always go back to the constructor brush because i really believe it's the best brush for cleaning amongst the brushes i have, so i probably clean 90% of my daily work with the constructor.
I have changed the bristle layout to suit myself, which is one of the benefits of this brush you can buy different bristle packs and "construct" your own brush.
The biggest drawback for me is the "cannons" on the top they tended to get knocked and lost in the early days, i have modified it slightly and this problem as gone.........i do believe he is in the process of replacing the cannons with a solid bar and this can be retrofitted............The cost was about £130 incl postage, i had a mad moment and bought it
