gotta get used to em
its all personal preference and personal attriutes.
im 6'2'' and i have 190 firstbloods. i ski BC, pow, and trees mostly but whenever i take a lap thru the park, ill hit the occasional rail or 2. until you get used to longer skis, just hit rails like you would urban. just pop n hit em from the side instead of staight on straddleing th rail. once you get used to the pop and the length you should be able to come on straight forward.
but yea, if your 6' then those skis are on the small side for your height anyway unless you ski ONLY park!!!
