Hmm you're still missing the point.
Jum is the name of a specific technique. Tan, bong and fook are NOT. It is these three 'seeds' I am referring to, NOT the three forms as the three seeds! Besides, without adopting the seed idea into the forms from the beginning, your tree will be weak imho.
You have to have a creative cycle first too, of which tan, bong, fook is not. Learning how to fight only is also not so creative...
