Replying to Steezy Pole Length

I have some 44" Line Pin poles that my parents got me for Christmas that are the "correct size" for me (my elbow is 90 when holding the basket of the pole upside down)(I'm 5'9"). Although they're great for all mountain, when I ski park I
a) look like an idiot
and
b)whack rails with them all the time when spinning
so obviously I want some shorter poles. I'm thinking of cutting some old ones down or maybe just buying new ones but... What size should I use?(in inches) for maximum steeze?
