I was taught WS during my teens, but haven't touched a board again until now. Back then, I was shorter and lighter. Now I'm 6'4" and 230 pounds.
I purchased a Mistral Prodigy and a 6.5 Express sail.
I have researched and have plenty of theory in the noggin, but am having trouble applying it. (Kinda like knowing how Chess pieces move doesn't make one a Chess Master).
I can tack, I can Jibe. I can keep my balance (that's a good one, I hear!

Here's some of my issues...
--I've read I should lock a larger sail further down towards the nose of the board. Is this true? True of a shortboard like the Prodigy too?
--I simply cannot sail beyond 3 or 9 on a clock face, with the wind blowing from 12. I find the best I can do is get up some speed on 3 or 9, then turning to 10 or 2 until the speed drops to 0. Is there a specific stance that allows consistent sailing in these directions?
Any assistance would be greatly appreciated!
Also, if there is someone in the Maple Grove or Plymouth area willing to spend an hour or two cleaning up my stance and bad habits, please let me know! I'll throw some dollars and bubbly your way to make it worth your while.
