While I do have a DA Badger 150, the 100 is still my goto brush unless I am doing camouflage or shading. I am on my second 100, replacing my first one after forty years.
Only thing I don't like about new one is bottle adapter is press fit, and it occasionally falls off. I have tried everything I can think of to get a tighter fit, to no avail. Not a big problem but it can create a mess when it falls off.
