Anyone have any idea where to find a quality wall bag? I haven't had any luck finding one where the grommets don't rip or the zippers don't bust. Leung Ting used to put out a good one but I can't find it anymore. Everything Wing Chun has a 3 section canvas that I like but it's out of stock. Which leads to another question . I've always used canvas wall bags, the leather ones seem like they would burn your hands . Anyone have some insight ?
