Hello Fellow Stringers: I have never done one of these frames before, but I have done other O Port frames, so I do not have questions about the stringing of the O Ports. My questions is that this frame has some non 0 Port sections (top) on the top of the frame, some of which have grommets and other that have no grommets. On the top of the frame there are 6 or 7 unprotected un-grommeted areas and 6 grommeted areas that have full grommets thur the frame and out the other side. There are 4 that are used for tie offs and two other it seems, random grommeted holes. I just got a brand new grommet bumper set from TW. Please help I am confused. These areas that have no grommets look very unsafe and look like they should have some sort of protection. The only protection I can see is the bumper guard on the outside of the frame which seems safe but the inside of the frame looks scary. Am I missing parts? Do I tube each one to be safe? I called TW to make sure I had the correct set of grommets. One last question. I also am in need of one piece stringing instructions of this frame. Regards, Steve Any helpful comments are welcome.
