That braid is fine, use the widest that is practical and easy to work with. No need to drill extra holes if existing holes line up. You don't need to swiss cheese your frame, just make sure the existing holes are clean and maybe use a bit of dielectric grease or silicone to keep them from rusting too much.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
