I don't follow... if bfta = nefta ft = nefta hft = ukahft then that must mean you can use a bag in ukahft? It's been a while but i'm not sure you can... if that's correct, then somewhere along the line they aren't the same.
On the nefta page, the only rules i can find are from 2010 (which won't be the same as the current BFTA rules) and another set which mention that if you don't want to kneel you can stand.
Is there some other set of nefta rules?
