Replying to I margarine, help me butter. Will a flexy ski help?

Alright I try to butter, but my skis are stiff as fuck, and that is not going to change. I am 130 lbs, 5'10. Im scrawny as fuck and can't for the life of me consistently flex my skis. I have stiff boots. I am just looking for a ski that can help me actually butter. I am wondering what the flexiest ski is out there that is not the Line Mastermind. Am I just doing it all wrong? Are some skis better for buttering than others? What would you recommend? I currently can halfway butter, more so margarine. I need new park skis, dont care what size or what brand as long as it can hold up. I am not crazy big or disastering huge concrete ledges, so most skis should hold up for me.

Thanks for the input.
