Oh man you guys can be like a bunch of argumentative old women some times - like I said the whole thing is six one half dozen the other, but evidently thats still not good enough. I said gravity wasn't the be all and end all but was a factor - how big or small is open to conjecture by the user.
You want something to refute? Well as stated EVERY brush manufacturer that has brush care recommendations on their website or with the brush SPECIFICALLY states that the brush is to be hung bristles down after use. It's that simple.......now I'm not saying I know more than them, in fact I openly admitted my knowledge is amateurish in comparison. So bar room theories and year 10 physics knowledge aside I'd say it's a very bold move to say one knows more than multiple organisations who've been achieving excellence in their said area for a combined several hundred years. So find me one mainstream brush maker who specifies that they should be stored post use bristles up...
The sticker orientation? Please - one's got nothing to do with the other and putting it forward is little more than absolute guessing. Likewise saying do the co's sell brush hangers (which quite a few of them do, presumably as it's an easy way to mark a generic product up by 1000% simply by putting one's logo on it) is a pointless matter - as it's like saying does the milk company expect you'd store their product in a fridge, given that they don't make refrigeration devices. One's got nothing to do with the other.
I'll say it again I'm sure there's next to no difference which way you store your brushes...up, down, sideways etc. I agree they generally look better visually if stored handle down and I'm sure most people store this way as it's most convenient - and at the end of the day I think thats what it's all about, whats convenient for you.
PS. Hopefully this post doesn't read 'mad' - not meant that way or in a personal manner against anyone - is just a discussion (albeit a trivial and very YKW-ish one) of the pro's and con's of something silly.
I have to say this place reminds me of an old joke,"I went to watch a boxing bout and midway through a game of ice hockey broke out!" - which if you know the nuances of the sports in question is more meaningful but someone starts a thread here on a given subject and it goes completely of track and onto something absolutely different. Go figure.
