I haven't used the Pro Greens so take my advice with a grain of salt but anytime I've picked them up in the store they seem a bit large and heavy for their respective ratings whereas the Avids seem a bit lighter and have a model for pretty much everything inshore. If you're interested in G. Loomis, I suggest checking out the E6X rods. For trout the 7'6" 6-12 model is excellent.
I own both. The Avid rod is a bit nicer than the Pro Green, IMO. I don't think you'll notice a difference in the sensitivity, but the components and build quality is better with the Avid. Frankly, they are both quality rods and I don't really thing you can go wrong with either one.
