Different strokes for different folks.
2 seasons ago I rocked 52cm poles and I'm 6'2. WAYYYY too long. I felt like a boner. Unnecesary poles plants especially when riding park. How I managed to walk away with two unbroken thumbs still amazes me.
Now I rock poles probably 30cm. Bought the surface poles and chopped them down until I was comfy. With my skis and boots on, my arms bend slightly when my hands rest right on top of the grips.
They don't get in the way and I can still do effective pole plants. ANDDDD they look steezy. Always a bonus.
Now I'm rocking no poles typically. However, I just picked up a pair of Line Darts that I plan to chop SUPER short just for shits and gigs when I'm in the park.
