Greetings. I am struggling with length choice and was hoping for input. I am 5’ 7” 180 lbs 57 years old. Consider myself expert for my age and am fairly strong/ fit for my age. I am in Northeast and ski mainly frontside but venture off piste and head west a few times a year. Have gotten rec for both 172 and 165. Not sure if going 165 would be better for a more playful feel, but then worry about stability at speed. Appreciate any thoughts. Thanks.
