the m-80 5th line attaches to the kite at three points spread accross the leading edge.
this not only takes the stress away from one point for attachment but if the kite rolls it doesnt tear it in half, it just wraps around, then i have found every time the line then goes around one side then up comes the kite.
just means you have to go in and re-run your lines as you have a wrap around the 5th, but you can get to shore easy.
this only normally happens if you ar in rolling waves tho.

i have the 12 & 7.
the 7 is unbelievably fast if you throw it around. it is a wave riding machine, just need over 20 knots.
the 12 gets goin super early and is a tank. still getting used to the power.
i bought this combo to replace my 8 & 12 normal setup. it maybe has a little gap inbetween but i am still working out the limits & line lengths/bar lengths etc. tho on a surfboard and unhooked the kites get going remarkably early.

the one thing i found with these kites is they get going early, tho as they are low-medium aspect and sit pretty far back in the window you dont hold your ground as easy in the lighter days, but i dont really care too much on that cos most others are walkin anyway.

the best things with these kites are:

-the bigger kites just sit there like a boat so you can go for it.
-all kites turn end on end so are sweet ass for waves
-when you are turning they dont yank you off your edge like a lot of the higher aspects do. they dont lift you either so you can hold ur edge to ride waves in control.
-construction is great, a definite improvements is seen every year with lf
-spider inflation is sewn in, a handy thing this, makes rigging up fast.
-look sic (important!!)
-price is super affordable

anyways my opinions on the m80's and everyone that has bort them has had grins from ear to ear at scabbies.
dont know a lot of the cabrinha C02's as not many around perth.

Thanks for your advice I will be checking out a few kites when back in town soon.

i have tried both 12m kites several times. the m80 is a nice o5 model kite. as for the co2 o6, MORE POWER, you will jump higher and the wind range is incomparable. If your a heavy or strong solid rider you will notice the co2 06 holds its shape while turning under a mass of load while the m80 loses shape and turns like a truck under pressure.

The m80 is 05/06..... theres no new ones anywhere yet for aaaaages
