To easily see the plastic sheet in the middle of the CA hinge on the Gp ones all you have to do would be to add a little epoxy or glue on the Ca hinge and let it harden and the make a little cut in it. Then rip that sucker and you will seea little plastic sheet in the middle...... I found out the hard way(almost......) I think ill give a littler haller to the Gp Tech support and find out what their explanation for this is......Raise hell maybe.........im open ears at this point b/c It's looking like ill go switch to Robart hinges or nylon hinges..... thanks
