I use heavy duty zip ties too, all of the straps gets so expensive. It took me a while, but I got used to it, just making sure to step on top of a frame piece, not a poly span. I also used pieces of wood to shim between two spans (cheaper than fittings) that worked pretty well, but I don't do that any more. Yes, it's nice to be able to strap stuff to it, anywhere you want. But beware if you are doing so in big water and NOT going through/around a frame piece. I've never had carnage that way (and had a Class IV flip) but it seems a bit of a risk. For important stuff (toolbox and camera box), I make sure the strap goes around at least one frame tube.
You could also try doubling it up, to reduce the flexy.
