This is my second season.
In my first season I went out from August to October with a 200 and a 5 mt sail.
Now I moved to:
Ezzy Freeride 5.5
JP Funride 145L
Ezzi RDM mast
I am going now to buy a 6.5 Ezzy Freeride for the light days (10-15) as my 5.5 doesn't plan before 15-20 knots; probably because I am still learning.
Personally, I will also suggest you two fixed lines, 22 and 26 and start with them as soon as you can.
Leave the footstraps for when you will be able to plan on a harness; before that they are useless.
Last one, learn water start ASAP!! It will make a huge difference.
