So have you been able to try/comapre the new and old 10m skypoles. ?
Just magnified both brushes bristles, they look the same except that the Tesco ones are 1/2" longer.
They both have the intermix of flocked and monofilament, the Tesco one has 6 rows across and the old bentley 5 rows. I think the tesco one splays better because its got longer bristles and they are closer set in the brush and do not stand off the glass so much.
ells teeth youll have me counting the bristles per shank next :
