This may be rather unconventional, but Kris Overstreet is slowly winning me over with his characterization of Cherry Berry in Changeling Space Program and The Maretian.
With a love for flying that almost rivals her unabashed addiction to cherry. Balloons, gyrocopter, or bi-planes, if it can keep you off the ground, she want to fly it. In her backstory, she worked various odd jobs for years around Ponyville, saving up bits to fund her passion for flying as an earth pony.
