Gregob - you can get planing on bigger kit than a 6.2m but it's a different sort of planing. It's all apparent wind and you have a huge rig - it's like driving a bus versus a motorbike.
If you want to get better, it's better to face that fact that planing with a sail bigger than 6.2 isn't worth doing.
This isn't to say windsurfing in light winds isn't worth doing, just that planing at all costs isn't worth it.
You have an ideal set up to work on all aspects of rig handling - you can learn all the tricks in light winds and then plane when it is windy.
I'm 85kg and my biggest sail is a 5.5m which I put on a 108litre board. It gets going pretty easily and when it is going, it feels like I want to do things.
Hey Ginger - it sounds like what you are saying is I should be patient and wait for wind that is strong enough to get planing with 6.2 mt sail. It sounds more like a measure of patience than skill as where I live I would basically forgo the exilharation of planing 360 days a year! And knowing my luck the other 6 days would be week days

I don't consider purchasing gear that suits my skill level, board, weight, and prevailing conditions, to be trying to plane at all costs.
I have spent a fair amount of money over the last 6 months on windsurfing gear and like most people when they are new to the sport, I wish I had chosen differently with some items. Like the funster, If I could choose again I would probably go with a large version of a performance model board rather than a learning board; I would go with slightly more volume as this would be better in really light conditions and also have come with a larger fin. I would probably also have purchased one or two different fins and I would have gone for a 460 / 400 mast combo instead of a 430/400 combo and I would have gotten a 7.5 mt sail with the 6.5, 5.3, 4.5.
Had I purchased a 155 Lt Excite Ride or Starboard Go a 460 mast and a 7.5 mt sail, I would be planing about 50% of the time.
But we all make the best decisions with the knowledge we have at our disposal at the time. Probably the largest contributing factor in my lack of planing at the moment is the fact that I wasn't born and now living in WA. But selling the house and moving family to Perth might be a little too obsessive
