Rubber lip too hard

I think the rubber lip of a stripper too hard, that is, the latter is too inflexible and not well adapted to the disc. The result when removing from water on the disc are then places where the rubber does not come to the plate, are formed water-strips remaining on the disc. One must then go over it several times, does not look so great because "margins" can be seen.

That's better, why not buy recommendation.
