I'm on the fence about buying straps. I'm sure I will end up doing it, and it seems like Phenix is the way to go, but I'm not convinced yet. The strap that came with my Innova bag has held up pretty well so far - do the quad straps really make that big of a difference? I carry about 20 discs and a few bottles of water, but the weight doesn't really bother me with the single strap. The single strap also makes it really easy to pick up/set down, which I feel like would be more difficult with the quad straps.
Basically I need someone to sell me on these things. Any takers?
