Best all round beginner to intermediate board this year would be the Nobile 555 09 in my opinion. If you kite in 11-16 mostly then the 140 is ideal and it will still handle 25 no worries.
The 555 has been excellent in chop, upwind ability is awesome, plains early, still plenty of tip flex for advanced riding and the toeside is really good. Have used in surf and flat water and it will handle both with no hassles.
Not bias as far as brands cause we can and do stock all the suggestions you mentioned, but the 555 has been a stand out for us this year.
Have ex demo 140 if you want more info email me.
