Don't let these guys scare you off from your original options. Sounds like you've been riding a long time and are used to a long, stiff, cambered board. Going to either of the options you listed will not be an issue, after you get used to the new board and alternative profiles after a day or two. Although the Raptor is regular width, you should be ok, might be pushing it a bit with a size 11 on the 159. Stiff yes, but plenty agile due to the width/sidecut. I had a great time bombing on mine, and had no issues with it in terms of maneuverability. Flagship is prob a great option also, more familiar length and camber in the middle, although it is damn stiff.
