You actually did quite alright with your first setup considering. Given your weight/height, I'd definitely recommend something in a 142-144 range for you. As you mentioned, you don't want anything too wide for your sz 5.5 feet and a longer board will also take more exaggerated effort to initiate turns, not to mention potentially heavier while riding the lift, carrying the board, etc... I'd also suggest something with on the softer side of medium flex to be more fun and forgiving since you're just not gonna flex the board the same as a chick that weighs 20-30lbs. more.
