catagni or peng?

Edit Post

I am confused on who to goto for a faster yet safer recovery for 7.5cms on tibias.

Peng is definitely faster because of LATN and safer in the sense no ATL(his device is great). Only worried about permanent knee pain.

Catagni coz hes like the God for tibias. But external would require to do 9 to hit 7.5 after shrinkge. And obviously greater recovery time.

Anyone heard of permanent knee pain from pengs patients after nail removal?

please help me decide.

not bothered about place and travel. I fear of ATL that catagni would do after 5cm. So device is the drawback from catagni.
