Look at any turboprop parked on the ramp. If the props are feathered, you're looking at free turbine engines. I'm prejudiced, but I think they're the better way to go. My ladyfriend disagrees. She flew Dornier 228s, ATR72s, and SAAB 340s before she went on to jets, and she likes direct coupled turboprops. Now that she's retired, she hasn't touched an airplane since.Same on the other P&WC turbines, the PW100 series for example, all free turbine engines.
