Puts anorak back on.I do have two identical Omega boar brushes so tempted to do the hanging vs standing test...
Other factors might play a roll - how well the brush is broken in for example.If doing the test I would use two brushes at the same time because I am not in control of conditions like temperature and humidity.
What where the weights when you started to dry?Ok, brushes are currently drying, one standing, one hanging, will weigh and compare after 12 and 24 hours and fill in %
12 hours: standing xx% dry vs hanging yy% dry
24 hours: standing xx% dry vs hanging yy% dry
