The biggest gripe I have about playing with my Vic Firth brushes is that once you've fully extended the brushes the triangular bend in the metal handle gets in the way of playing - it's always digging into my palm when I try to play.
Today I had a lesson on brushes playing with Dave Hassel. He leant me some brushes for the lesson and he'd bent the ends of the handles at 90 degrees. It made a huge difference to comfort as they didn't get in the way at all. If you play with brushes I recommend trying it.
