I really enjoy my mountain twin. You can beat yourself to death thinking about all the different boards you can buy, but from what you described the mountain twin will give you everything you need, and a lot of it.
And Francium, I don't know if you are joking or not...but I hear you on the hiding boards from the wife. My stash spot in the basement was recently discovered. To be fair, I had reasons: two for collecting, one for thrashing on a friend's backyard set-up and two for the hill. I had some explaining to do. She still doesn't get it, hahah.
Haha nope wasn't lying. Mine are hidden in my wheelie locker she never goes through the boarding gear luckily.
