Fish Hunter,
My new Koffler 20' x 72" has a 200 Merc with the oversize pump... Talk about torque and power, she runs a plane at about 3300 rpm's with 4 guys that total about 800 lbs, and top speed, well no thanks not necessary.
Grass Hopper- I've ran all but the sport jet, but know a couple of guys that have them and are scared to run the shallows on the lewis at 900 cfs, but what boats have you seen run 2-3"s of water that are 20' x 6'? And holeshots, the koffler comes out of the hole on plane and there is no A$$ drag and will come out of the in literally a 1/2 of a boat length.

Highliner-
It all depends on the fishery you want to fish, but the koffler, Alumaweld, Willie and Thor Built, will do any. If you want to fish small rivers, Columbia, Buoy 10, Ocean you can do it... Yes you take a little bit of a beating when on rougher water but they're solid they can handle it. As for room, I've never seen more in a boat as a koffler. I've got double rod racks 6" wide the length of the boat and the rods stay completely out of the way. There's two removable box seats and two other seats that are removable that mount to the deck. More or less you have a gutted out boat that is top notch for boondogging. You have a boat that will cover any fishing condition except if you want to sit under cover and out of the rain with a windshield. But if you want that then you want a boat with limited availability for fishing styles.

As mentioned before I've ran Alumawelds, Willies, Thor Builts, North Rivers and have caught hundreds upon hundreds of fish from sleds, so I hope you'd value the opinion. You know that you're as good as your equiptment allows you to be... As you can tell I'd like to beleive that the Koffler is the best and until I find something that does it all better then I'll go with it.
