It seems tough enough but the problem with using it as a protective or performance enhancing backing is it is too short to provide the continuous fibers needed to add performance. To cover the length of the bow splicing is necessary and defeats the purpose of an elastic backing. I suppose you could do a Z or W splice and then wrap the spliced area with sinew but who knows how well it would hold for tension. Sounds like a good idea for an experiment.
