I had a pair of 189 hellbents and they were awesome! Im about 5'10" and they didnt feel too big and floated soooo sweet...and riding switch was amazing!
So depending on how tall you are I would say buy the 189's its worth it
I got a pair of last years hell bents in 189 drilled once for salmon s14's and only have 3 days on them. I would be willing to part with them for $500.
