I prefer the stick. I had the wheels on the SD1 and now the stick on the SD5... and back again to the wheels on the Audya. Unfortunately, the Audya has the wheels located about an inch higher than on the SD1. The fact is, though, you can adjust and become comfortable with whichever one you're using on a daily basis.

AS far as proper/improper usage, you have to be familiar with the instrument you are trying to emulate... pedal steel guitar is a good example. You have to know just when to mod and when to bend, and how much, for it to sound right.
