I think in terms of this and next seasons skis, the tcs might be the most flexible. The al dente are great but only once u break them in good. the should riders are pretty buttery too but not as much as the al dented once u've broke them in for a season (they can get reaaal buttery)
it really depends on your weight/strenghth, if you're quite heavy, know how to butter well, any quite buttery ski can become real buttery after a while. I'd look in the flatypus toros as well, they'd be cheap from last season or before, and king of butter didn't too bad on em xD
