Parachute size is not your only concern. A 30" parachute will slow your rocket's vertical descent rate but won't do anything to its ground speed if the air speed is high due to a significant wind. If you're concerned about the fins being snapped off due to an angular impact, only fly the rocket in calm conditions.
(I had a similar problem with my Feuerlilie F55https://www.macs.hw.ac.uk/~adrian/rockets/f55.jpg, whose wingtip fins like to snap off given any provocation. I gave it a 75cm parachute and it still lost a fin when, due to a significant wind, it hit the ground at a fair horizontal speed.)
