So after its first outing, my first impressions of the brush are very positive. Passionately positive.
This brush is fun, the first 2 pictures illustrate the two lofts I used with the brush for a 3 pass shave. I also had a lather at 46mm and 60mm, to appreciate the 'parameter feel'.
As expected you can go from scrubby to mop like feel, in a matter of twists. Quite a lot of twisting come to think about it. It doesn't click or provide other indication of loft, at least with this prototype. You can even experience those cloud soft tips having the brush set around 54-55-56mm. Gorgeous.
I kept the loft low, loading from a hard puck, then added to the loft to face lather.
At 46mm it's very scrubby, no scratch but hard backbone. Not uncomfortable either. Little splay.
At 60mm it is very much mop like. Large splay, ultra soft face feel.
First pass; I easily dialed in my optimum loft, to provide 'that exact feel' I like. I would put this at around 50mm. A slightly scrubby massage with good (7/10) backbone (considering D01 2 band at 10). I have also asked Bernd to use the hairs he provided, they remind me massively of the 2015 LE (best hair so far IMO).
The 2nd pass was around the 56mm mark, and cloud soft. Controlled splay and a delight to use. Incidentally no flow through issues with either knot loft.
I found the gap between the bottom and top of the handle not to be as significant in use as it is when not. However at the higher lofts (beyond 55mm), a scrubbing circular action caused the handle to twist back on itself altering loft, so this needs to be addressed. The lower lofts have no issue. A nice feature is lowering the loft to push up lather. Also being able to remove the entire knot, for cleaning purposes.
The handle does not rattle or vibrate as such at the highest lofts. But could certainly feel.more solid.
Having a different knot size and thus face feel from loading to lathering is excellent. I thoroughly enjoyed the shave and being able to start scrubby and then 'spongey' between passes was great too. Very promising start. Apologies for the ramblings, will provide a more factual review tomorrow
