Sort of shopping the net looking at a Simpson brush - the Commodore X2 specifically. What I have noticed is that at least three different purveyors list three different loft heights for the "same" brush. Am curious as to why. Should one suspect that each of them orders the Commodore from Simpson with different lofts? Do they each measure what they get from Simpson and individually pick a loft height to advertise, recognizing that there will be some variation in manufacturing? And when one wants to buy a brush, would it be reasonable to request that purveyor to measure for the loft you wish from among the stock on hand? Thanks for opinions /facts on the question.
