They are tough because they have two shear lines, but you said you looked it up, so I won't go into it. The first one I picked to the control position was a life changing event for me! I love picking SFIC cores, and Peterson makes some special tension tools that can help you try and grip the holes in the bottom of the control plug. I've got them and sometimes they really help, but other times they do nothing to help you pick it to control position.
Good luck, keep at it, and happy picking!
