The Raptor is more of a big mountain board not a pow board. It rides pow well but thay is not it's specialty. Set the stance back all the way. I think the Prospector will be a great pow board. I've been using the 161 split for weeks but it has been all spring conditions. Still the shape is pow friendly. I believe there is a solid version.
Venture boards are nice. They are built tough which means they are a tad on the heavy side. They are not as quick and easy to initiate turns. My thoughts is because of the flat base. It takes a bit to get used to. Expect to need a few runs to adjust if you do not have experience with that profile. The float is some of the best though and breaking trail is great. The tips just dive up. Lots of traction when skinning too.
