Perhaps it's the glider pilot in me but I always coming in high and slip down not necessarily aggressive but I do slip. When I got my private license the most annoying thing for me was the fact that a C172 does not slip at all compared to a glider.
The way I look at it, Altitude is my friend. You can always trade it for something. I don't like dragging in on the prop. I always think of what were to happen if the engine quit. Just my thing I guess.
