I have a really old version of that model on my switchback xt, and have the ultra on my heli-m. Love both, the wheel on the ultra or the kingpin is easier to adjust the yardage on quickly, but the slider is not a big hindrance on the lite. When hunting I keep the knob untightened, which can generate some shot noise, but not too bad. Here in the Midwest I generally have it set at 20 or 30 and keep it there. Usually spur of the moment shots are close in the woods and longer shots develop more slowly, and there's time to range and dial, which is easier on the ultra.
