What should I look for in a surgeon for external tibia?

Edit Post

I'm looking to do external tibia, and there is not a lot of information on this forum about it. I remember Kilokhan said Parihar told him a surgeon should have seen a lot of complications so they know what to do if things so wrong. However, from my understanding, external tibia is the most primitive and likely easiest surgery to do. Aside from pin infections, what are other complications that could happen? I read somewhere that even though pin infections happen more often, it is much more fixable than something going wrong in LON.
Please correct me if I'm wrong here. I'm also open to suggestions on what doctors I should go to.

I heard the Taylor Spatial Frame(TSF) is the best frame. What are the differences from HEF? From another post I think HEF is better if you want to lengthen longer, which looking at your signature(hello starting height twin!) is desirable for you. Dr. Pili requires Achilles tendon lengthening after 5cm. I plan on lengthening 3cm on tibia and more on femur for the future so this won't affect me, but I see you plan to lengthening 12cm so you should look out for that.

Thank you for the replies guys. I have some more questions and I would be really thankful if someone can help me out here.

So how much better is TSF compared to the classic Ilizarov frames? Is it really necessary? From what I have gathered so far, TSF allows correction of bone misalignment. But, Parihar and Dhawan uses Ilizarov while still correcting misalignment with software. Solomin and Kulesh also use hexapod but I don't know what they do.

Does anyone know who are the doctors that uses TSF? Besides US surgeons, whom I will ignore because I'm a poor young adult, I only know Giotikas.

So far, my list includes Dhawan, Parihar, Solomin/Kulesh, and Giotikas. I will list the cons of each.
Dhawan- He is Indian and only Parihar is mentioned when talking about good Indian doctors. Will have to do more research.
Parihar- Hard to be accepted by him. I have a friend from Mumbai so I will see how this pans out.
Solomin/Kulesh- Said to have too much nerve damage cases. Also read two users(Android and a commenter on his dairy)who claimed nerve damage from them.
Giotikas- Most expensive on this list.
