Even at your light weight the 147 cc is going to feel loose and jibby. If you want a board that will be different then the riders choice is the better pick. Your going put on a little weight at some point.
Being a Never Summer fan, have you considered something like the Proto? More of a mid-flex but a true twin, built like a tank and will take you from all mountain to pow to the park. Something to think about. Shortest they make is a 152. Dont know if that would be too long for your feather weight.
