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.
My husband is riding a Raptor 164, loves it for being very agile, fun to carve AND great in pow.
I'm on a Flagship 158 (I'm 123lbs). You'll find some of my impressions here girl-jones-flagship-good-idea
guess if I'm pleased with it
I actually tried it yesterday in dense trees. It's easy to maneuver. The Flagship is damp, yes. I landed a little jump out of pow on the flat track with my legs not bent enough to absorb. The shock-energy was transferred through all spines
but that's my fault. Bend your knees, ride low and you'll have a lot of fun.
Some of us didn't learn/progress on noodley bananas. We had to learn how to manhandle some unforgiving planks lol.
maybe that's the reason, why I don't get the point of the flagship being hard to ride; I had to learn an old Custom X
I'd recommend, you give them both a try and judge by yourself, if they fit your expectations and riding style.
