Pak Alan, probably these 2 photographs of ganja can satisfy your request athough not too obvious I think, sorry. Somebody told me that pamor nyekrak is a term of pamor miring type which refers to rough and sharp surface, seems like done by kamalan method (again, I do not know how to translate kamalan word in English). Frankly, I do not know about that
Regarding pamor luluhan, actually no one has told me the meaning of that, but I ever read that pamor luluhan is related to pamor Pitrang
Sorry I cannot explain anymore because I do not know..
