a 191 caylor might be a bit much for what he is looking for, i dont know how they compare to the new jeffreys though. the bentchetlers would be a more forgiving ski for someone just getting out of the park. a 181 caylor might be perfect, it would be a big jump to go from a softish 176-ish(guessing) park ski all the way to a 191 caylor.
i am 6', 175lbs and have 191 caylors and 192 bentchetlers. to me the atomics are a little more surfy and playful, whereas the caylors are stiffer and very confidently charge any line in front of them. dont get me wrong, they are still playful but it takes a lot more energy.
