Quit your cunting...
ZF must get their act together... no tourbillons from them unfortunately ever so we will not see them in the future, but they gotta step up their carbon game. JBF has it down, ABD is not needed in my opinion unless you want to mod a KVF model.
Crystal ZF is still the best, but JBF is very good much better than KVF.
If one were to mod, it would be great to combine JBF and ZF parts if possible... don’t think it is though...
