I'm looking pick up a light wind board to extend time on the water

(Port Philip Bay)
73kg and currently ride a JP FSW 85 in 17 knots + but looking to get out in 13-16 knots with < 7m rig.
Have narrowed it down to a Magic Ride 105 (68 cm wide) or a 2014 Rocket 115 (66 cm wide). I also see that the 2015 Rockets have gone wide 108 / 73! Anyone ridden one of these?
I'm after early planing, chop eating, nice gybing and comfort. Speed good too
My question is which way to go for a light wind board - more classic 2014 Rocket shape or the new breed of thin, wide, short, lower volume "potato chip" boards?
Any advice or comments much appreciated.
