I can't split torsos! Help please!!

It takes time and practice. Sometimes it's easy to do and sometimes it's very difficult. I split RA15.5 Heidenreich's body perfectly the other day without one stress mark or bending it too far. But I also split a Mysterio torso and it was quite a bit harder. I had to use an elastic band to keep someone's head on! Luckily it was Psicosis and he always wears something around his neck anyway, bandana or necklace. It would seem out of all the old torsos cruiserweight is the hardest to split.
