This sounds like the ski for you man.
104 waist, so it's at the top end of your waist size, which means more float and these things are as light as anything.
I would also maybe recommend going up to the 188 at your size. you may grow antoher 2inches and then you will definitely want the 188, they run out at 186 i think. The 178 will feel short already especially if your mounting close to center.
It's really nice and soft for boots and the tail with the extra rise works well for switch.
I'll have a look around and see what price I can find it for.
