I simply don't use trick, it's not really needed if you have spikes because you can defeat Snorlax / Porygon2 with Hidden Power Fighting anyway. I see the usefulness of Trick on a Choice Scarf set, but Choice Specs Chandelure doesn't really need to use Trick. I mean, if you can't afford supporting Chandelure with Spikes, Trick is better because you can beat Snorlax / Porygon2 with it or at least cripple them for the rest of the match. I'm not saying Choice Specs Chandelure is the best set though (it was much better on round 6 imo), and I agree Subtitute Chandelure is better now. As I said, Specs Chandelure niche is wallbreaking so that's the reason to use it over other sets.
