I have been using the H2O rods for years now. My favorite model is their foam handled $79 model. It is very light and sensitive. Previously, I have used several other higher end rods including Kistler LTAs, Falcon Cara's, Duckett, and years ago the high end Allstar rods before they become a commoditized rod. I absolutely love the H2O rods. From what I have found, you would have to spend over double the price to get a comparable rod.
The nano rods are newer for Academy and venture into the mid level rod market price wise. I have used them a fair amount. The nano resin makes the blank a little stronger and a touch stiffer in the same action. I like the $79 version better because the cork handle in the nano rod does not fit my hands as well. Additionally, I like the matte finish better.
Note that a few times per year they run some good sales on them. Keep your eye out.
Action wise, I live the 7' MH for a wide range of applications from spinnerbaits to traps to shaky heads to light Carolina rigs. Their 7'3" H is great for heavy Carolina rigs and flipping. Their 6'8" spinning rod is a great drop shot rod too if that fits your fancy.
Not saying there are not other good rods out there. The H2O blue colored rods are just some of the best for the money IMO. I have not used the omen rods yet, but their reels seem nice. The Mojo Bass rods are good, but they are a lot heavier weight and balance wise.
