The 4*60 isn't a bad choice - just make sure you have plenty of power up front, certainly something a bit bigger than a .60. In strong wind, the best thing is being able to fly with authority, particularly when turning into the up-wind part of the circuit. You'll find that anything with a large wing area will get tossed around a bit, and you may find it floats a little on landing, but you probably already know that from your trainer.
