Need and want are different things.
I do not need a surf board, I want one, at least I think so as I really liked the Litewave DV8 when I tried it a few years ago, but I don't need it.
I think I might need a smaller twin tip board however.
Currently I have a Litewave Wing 161 as my light wind (awesome board).
An Ocean Rodeo Mako King 165 which was my first light wind board and now like using it in waves.
A Liquid Force 140 x 45 which was my very first board, although 6 years old it is in like new condition and works ok, so-so in choppy water however, too stiff and does not channel the chop too well.
But I also find myself sometimes overpowered with that board and I don't like being overpowered. I said "sometimes" and because "sometimes" is not "often" and I am a cheap bastard, which is why my oldest kite is a 2009 and my oldest car is 16 years old, smelly but still running, I'm debating with myself if I should spend $600 on a smaller board, like a 135.
How y'all deal with that question?
