I feel like a 2.5 twist dismount is a good choice in this code. Less chest landing deduction potential, less risk to ankles, and less overall energy needed to get it around, compared to a double tuck. I always like how Nastia did choreography right out of the landing on her 2.5 to finish her routine/mask landing errors. Not saying that applies in this code, but I just think it could look nice on Suni too.
I just came up with 2.5 out of nowhere cuz it seems obvious Suni could do it, but did my due diligence too cuz I was bored… turns out she actually did compete it in her 2016 floor routine.
