this is why I needed a vid ASAP. I am guessing hybrid is better scrubbing power, as it is in other range. What is equivalent to medium mixed?
Is the softest flocked
We will be shooting some videos as soon as we are able - at the moment we are slightly snowed under with brush assembling and fulfilling orders
A video would not actual help you with this question though as the difference between the two is all to do with the feel on the glass not how it looks in action.
The hybrid version of each brush has slightly superior scrubbing and is noticeable in that the centre natural bristles have more drag in use making the brush feel slightly sticky on the glass when scrubbing.
Some clients will like this, some will not. Personally I like the improved cleaning ability on snail trails and similar.
I hope that this helps with the choice.
The main reason for doing the multiple brush bundles is so that clients can try different versions for future reference. With these varieties there will be no substitute for trying them out against each other.
If you are still unsure I would say go for the hybrid version first as it is very good.
