Mine are 3 or so inches taller then me...park an fat skis. I just like the little more stable feel of a longer ski, and they float better and I feel like the spin smoother.
HAHAHAHAHA!!! for sure there has been like 87 threads like this.
but thats ok. I think for me the longer the better cuz im 6'2. so the average 181 park ski is like at my eyebrows. watever length works for you is good tho.
