I would not use an Allen wrench on the bottom cross tie off on a Prince O3 White. There is no grommet an Allen wrench under pressure is sure to damage the inside of the hole.
Also the awl should go in first so there is no blockage, then the string that will be tensioned to create the block, and finally the string to be tied off goes in the awl. I would still lubricate the awl with wax just as a precaution.
When you're dead you don't know you're dead. It's the same way when you're stupid.
