this is the first and only Fenwick I've ever fished. I would have a hard time paying $340 for a rod too. see if you can take them out in the lot and cast both of them. You'll be amazed at how "crisp" the TechnaAV feels. considering the materials used to make the AV you won't find a more sensitive rod until other manufs. catch on. depending on what you are used to, I'm sure that the HMX will be a step up. good luck!
