The question pointedly put is what is your favourite BOAR brush and why is it such for you.
Semogue 610 (red handle). This is my second brush, and first boar brush, so I can't really compare it to other boars. When I first started DE shaving, I bought a relatively cheap badger Vulfix brush because at that time, all the information I researched really pointed new shavers to badger, as they were always thought of as better performing. The recent popularity of boar brushes really got me interested in purchasing a boar, as I was mainly attracted to the backbone, and stiffness of a boar brush. Having used my Semogue about 20 or so times now, I love it. It still has that backbone, but is not at all prohibitively stiff, and I've noticed that the hairs have started to split, which makes it softer than when I purchased it. It honestly retains water well, feels great on my face, as I prefer a stiffer brush on my face for the exfoliating properties, and it just feels great. I don't have the biggest hands, so the Semogue handle is a comfortable fit. Lastly, it's an amazing looking brush; from the undyed, natural, blonde boar hair (which is aesthetically far superior to dyed boar brushes in my opinion), to the red and clear acrylic handle, this brush just looks cool; I love it.
Do you have more than one BOAR brush and do you prefer any particular brand.
No, this is my first and only boar brush. I do plan on buying another at some point. Possibly another Semogue, or an Omega.
Does anyone here use a Semogue 2000 - 25mm knot and 60mm loft?
No, I've never used it, but it does look intriguing.
