Buying together as a beginner?

Hi readers,

I was wandering what kind of board I have to buy as a beginner. I figured out that boardlenght is mainly weight and skill dependent. Personally I am 70 kilo but my buddy weight 105 kilo and having different feetsize. Is it possible/wise to buy a wakeboard together, with my buddy, or is our weight difference to big and will it result in a hardlearing time for one of us?

As far as i know their are boots which are "one size fits all" is it a good alternative for us i.s.o. buying 2 boards+boots?

Another question:
I am a prety good snowboarder and Im already familair with waterskiing (Like alpine skiing, at some point in time you want to go for boarding!)
I expect a fast learning curve will it be wise to buy a beginner/intermediate board i.s.o a fullblown beginners board.


Wait, my money-box is yelling at me....
It asks how much it will cost to buy a reasonable beginners/intermediate set.
