From what the dagger rep told me this weekend the GT series of boats wont do much playing other than surfing he told me to look at an Outlaw if I was looking at an older used boat, it's still a river runner style like the GT's but shorter nose and slicer tail. I myself have the Honcho its a bigger Outlaw for us boys over 200# and I love it I was lookin for a boat for the Girlfriend. Not sure about the Madness.
When I was shoppin I was lookin at the GTX an older 8.1 and everyone told me to go with the Honcho if I could find one as I would outgrow IE: get board with the GTX by the end of the season.
Don't do anything, just stand there.
