James, I saw one this fall and liked the look so much I bought one without paddling it. I have not been disappointed.
Best creeker I've owned to date and so far all of the outfitting has worked and held up--pretty much a hassle free boat from the get go. As mentioned, it's a looker and everyone picks it up and ogles it. I've had it out regularly all through December and January in CA on everything from micro creeks in the Bay Area to big water runs in the Smith River drainage. Me=5'10" and 180lbs.
Here's what I like about the Magnum: the bow has lines similar to a Phat (I went through three Phats and loved the boat) but the chine on the Magnum gradually tapers into a true planing hull on the stern, like a surf boat almost, with a nice bevel to allow control when deflecting from rocks or playing off them to get a good boof. The minimal stern rocker makes it super fast and allows for solid edge control in big, confused water. It's got that 4WD feeling when running over mank, but doesn't get swirled or spun around in big water eddy lines, boils or diagonals like most 4WD boats (when I say 4WD, I'm using the Dagger Gradient as my benchmark, displacement hull, pickle-boat that would climb over any mank you decided to bomb). To top it off, the Magnum is a relatively lightweight, easy to shoulder boat. I have no complaints in the two months I've owned it.
