I really wish the big wheel had some damping, or were heavier. I will probably disassemble the wheel unit and add something to make it "feel" heavier. At present, it's so light weight, and so effortless to turn, that the super high sensitivity becomes really difficult to manage with precision. The size is great for precision, but being light and overly sensitive makes it hard to make very small adjustments, which are often crucial in operating software -- tiny level adjustments, tiny position changes, tiny zoom amounts, etc.
