i'm not exactly sure what the flow easy in feature is, but you're main concern for bindings should be how they fit. you want you're binding to fit snug and in the center of the board with no toe and heel drag. you should definitely try out different boards to find the one you like. you're 1999 board might have a good edge to it, but i'm sure that after that many years, the boards flex is not the same as it was designed. board technology has definitely expanded since 1999, a new board will probably give you the confidence you need to expand your snowboarding skills.
