Hi Jamiee,
One more thing for you to consider is that 3.5 and 4.0 sails won't much very well with either 111 or 122 Carves. They'll be sailable but uncomfortable. Sort of riding a byclicle with the seat way to high

I had aC111 once and it's a great board you'll find it too big for the strongest conditions you mentioned.
If you choose the C101 don't worry you won't sink it even with a 6.0 sail. You'll have to get used to being more precise in your movements but that comes with time. Also you'll be able to uphaul if needed.
My two cents,
Ricbra
