HI , dimitri! if you ask me....
where do you kite ?? in land lakes ? or ocean beaches ?
what i mean is you have really steady winds??
either way, I think i would never buy a 14 ... not to my weight, much less for you
who are lighter than me.
2 kites quiver... 10 and 7 m (the 7 starts realllly early on a 165 lbs guy.. 18-20 knots already jumping)
3 kites quiver....
may be 12/9/6 should be more accurate answer... but
1º i would want a 10 for sure,
2º if you don`t get 30 + knots to often, it is not worth buying a 6 m..
My opinion, 12 - 20 knots spot , 165 lbs 10 and 7 is good enough
If you want 3 kites , 12/10/7 would be my choice together with a lightwind board
