board size

i posted this in the general wakeboarding discussion, but i guess it would be good to post it here too.

soo...
would a 131 be ok for me? i'm 5'7" and 130 lbs. i'm looking at the cwb lotus 131, which says it's good for up to 140 lbs. i've been riding the lf angel 134. i know one's a 3-stage and the other's a continuous...but beyond these obvious differences, how much of a difference would i actually notice?

also, would i notice much of a weight difference in these boards? the angel seems really light to me, but i've heard others say their lotus seems especially heavy? any truth in this?

thanks for your help!
