That's actually a negative. Problem with the heavy clasps, ropes and halters is the horse never actually gets a 'weightless moment' or true release. That's not good if you want a light, listening, attentive horse. That's why I no longer use rope halters at all.
As for the knots it's somewhat a misnomer. They do not reliably line up with any supposed nerve points anyway. They create focus points, so increase the pain response, but do not control any particular pressure points as is the claim.
As far as a halter goes, if it's good quality parachute rope (rather than the fibrous stuff) so it's strong and will last then it makes no difference. If anyone needs it stiffer or more knots etc then that's just hiding poor training skills. Just like increasing bit strength, or whatever.
