So my lws has a trade-in/trade up deal that seems like a truly good deal on Victor oxy-fuel stuff. I am thinking to replace some older Smith medium duty regulators with new Victor heavy duty ones. The salesman I regularly deal with is pushing me toward SR450/460 set but I am wondering about the heavy duty Edge 2.0 regs. Seems like ESAB has put a lot into the design and marketing. The cost difference is minor. Is there any reason to choose the old industry standard over the new Edge regs? Thanks,
