first things first - you cannot
alternate skis to mitigate edge wear/damage with the marksman. they have an asymmetrical sidecut. if you were to switch feet, you would be completely changing the turn radius of your skis and would drastically affect the way they ski. they would still be skiable, but would feel completely different and ultimately would not release out of a turn the same way. maybe i misread your comment, but just want to be completely clear about that.
i find them to be plenty playful but buttering/pressing has never really been my thing, so I can't speak to that. however, i am able to do basically anything i want with the ski, so there's that. i've done my fair share of park laps on them and they've done just fine.
