Set up my 1000gc balancer this weekend. Boy what a difference! I normally run doubles on my DC and I knew the blades were quite out of balance. When I engaged the blades, there was a noticable vibration. Well, I sharpened and balanced all 6 blades and the vibration is totally gone. Before, I would run about 3400 rpm while cutting... Simply balancing the blades brings that up to 3500+ rpm! Well worth the investment!
