Actually, it was primarilly the sound of the cymbals and high hat {with a few other factors} that led me to go back to using an acoustic kit. I felt they were the weak points.I've got all mesh heads with the td10 brain . The symbols could definately use some upgrade though, they are the stock older rubber ones. Great sounds but strange feeling.
They have some newer cymbals out that I was looking around for. Multi trigger and you can even grab/mute them.
