Excellent summary jiberjohn
my 2c - 'keen beginner perspective'
I spent time with hungrywave on the beach at RQYS on sunday
I was responsible for suggesting his planing style needed a little more oomph and action

I came home and wondered about the choice of a larger 120 board over an already successfully planing 110 Xcite ride for a 60kg pencil. I think there was the mention of being easier to uphaul and reviews of gybe ability were factors
I had already been scarred and suffering from ptsd after trying to get Morgs larger 160 atomic going at Weyba the same day that Jonesy gave it a go - still recovering from the blow to my self esteem! "Trainer board???"
Not all beginner/intermediate boards are the same - per jiberjohn - especially the narrow tail "modern style". My recent poor experience on a large gecko vs success on fat tail boards and my mate trading a ghecko for a much more loved and successful futura reinforce this.
So 2c from a intermediate experience.....
If you have difficulty getting onto the plane you aren't 'in the hunt' to be practicing carve jibes. Sail the board that gives you the most planing time = excite ride?
If the xcite is unstable in the uphaul = work on waterstarts.
If there is enough wind to plane there is enough for water start = uphaul not really in the equation
Went looking for excite ride 110 pro specs - couldn't find them. Did find this interesting thread
www.seabreeze.com.au/forums/Windsurfing/General/JP-Excite-Ride-110-versus-Jp-supersport-109?page=1with a nice wello video from greg in conditions that were a little bigger than when you were out hungrywave. Discusses board size also features input from jonesy
Plus this thread leaves me thinking the 110 is already big so suitable for your learning curve...

Duncan in the same conditions last Sunday 70+kg was comfortably planing with 120l futura and 8.1m Severne turbo. Just a data point.
Similarity my son 60kg was planing on Bic techno 293 with 7.8 race sail. Maybe you needed more horsepower?
