my first board, too was a morrow. a gift for christmas after borrowing my brothers old boards for a year... i've since ridden 2-3 morrows belonging to other friends, and can safely say the ones i've ridden a good deal stiffer than what you'd most likely want for park... if theyre on a budget i'd look into something like
blanksnowboards.com... yes theyre cheap, yes theyre blank, yes theyre owned by people like Jason Murphy, benson miller and a few others.
(ive ridden one i ordered for a backup stick for friends i take on weekend trips. sickest board under 400 mark ive ever been on)
not saying theyre the best out there... but definitely the best UNUSED budget board.
back on topic, morrow boards will handle the speed a new rider can throw at it... very fast board to grow out of skill wise for sure.
