You need 18 - 20 to get the best from the 14 Lith?
You obviously weigh a bit
I found once it was in those winds it became hard work, the pull was relentless. But that is what a delta style kite does, give oodles of power.
The 14 was recommended to me to demo, because many people use it with a 9m as their quiver, they are heavy people, so need the bigger kite. But the delta style kite does not match my technique anymore
A delta style kite lets you get away with not being light on your feet, you can just dig in and have that monstrous power.
I prefer something that needs to be flown and encourages you being light on your feet making yourself more efficient. Sure you still need to edge, but it's easier to kill off the power.
I very rarely use the depower straps. Even when overpowered I prefer to not use them. I either hang on, or come in and choose the correct size kite
And that's the thing, the way we are all so different and our styles \ technique is so different than each other.
Just because kite 'A' is good for me, doesn't mean it is for you. You might like kite 'E'
Having a demo of of the kites you're interested in should help you find what it is you
are looking for
One more important thing bigger people need a completely different kite over smaller people.
Over the years I have got better and I am much more efficient so I am more keen to fly smaller kites. This has given me the technique to improve my kite & board skills. Where I can use the same size as lighter people or the people on a SB when I'm on a TT
My first year I lived on a Zephyr, using it in 25mph winds. Now I hate using it in anything higher than 20
So, putting it back on topic. Denise should try a 9 Lithium or 9 Wave. Yes, the Wave is a Wave kite, a damn fine Wave kite at that. But it is also an outstanding freeride kite capable of working with a surfboard or a TT
My GF was using the 9 Wave yesterday in 14 - 23mph winds. I was on the 12m Wave. Both on TT
