I have ridden the blunt, conspiracy, and murray. I ended up getting the murray because of how thin it was and similar to my premier
The conspiracy is a super wide board on the tip/tail and the straight edge really works and is a good feature, it really locks your edge in. The landings are probably the softer than the other boards.
i liked the blunt more because of its narrow tip/tail, i think it has just a little more pop than the conspiracy. I felt the landings where a bit harder though. I liked how you could adjust the fin placement. But i didnt end up getting this board because it was just to big for me and rode way to high on the water. I only way 120, so my feel on the board will be much different than yours.
the murray is a super loose board, landing are about the same as the blunt. Pop is average, maybe just a less than the blunt but more than the conspiracy. Speed is about the same as both boards. Hope this helps, this is just my opinion so it might be different than someone elses.
