Have I tried enough

Edmand, are Plisson (the brand) how you come to understand "rabbit hole"? Wolverine Plisson are to steer clear of if you want to save money and keep what curiosity you may have with nice brushes to yourself. Plissons are very nice and really enjoy them quite a bit more than most that I have tried.

Silvertip Fibre ,that is either Muhle or Edwin Jagger .
Definitely something you should try .
And most probably will cement your
favor towards synthetics for good ...
