I think it is a good choice. Dr Kim has several advantages, but of course there are mainly 3 downsides: longer travel, no option to inrease the pitch even further with CTA (a method that I see very critical anyways, but if your voice is extremely low it may make sense to combine it), longer planned speech rest timeframe. I think none of this should matter to 99% of the patients, considering that the result will be with you for many decades.
Since you already decided, I will not make a full list of the pros and cons 😉
