NK tends to be better at Striking, but C tends to have better SD.Which is the "ITF proper"? ITF-V, ITF-C or ITF-NK?
V I would not recommend. Theyre a great Sport, but can be lacking in other areas.
PLEASE note that there are obviously exceptions.
Do the other ITFs have a similar by-law or are they more open to multi-organisation membership? <<<
I have no idea and ITFV supposedly passed this in 2009.
I started Boxing under ITFC - I asked Permission first, and They approved with encouragements.
I have heard of other Branches not liking the idea one bit though.
