A faster snappier redirect will translate into higher boost especially in light wind.
Yes and no, more exciting but not necessarily higher.

Yes this will help.

I tested the kite. expanding on your opinion, the lightweight of the leading edge and struts moves the center of gravity further back from the leading edge
Exactly. The balance improves

I had a chat with someone from industry lately...and the hope is that lighter materials will lead to a better performance similar like a foil kite.
In some regards yes. Many of the better attributes of a foil kite can be put to better balance and being lighter, though they are not everything they are certainly some important ones. You however are not going to even approach the performance of a high AR race foil kite by just taking a wave tube and making it light. This is a silly thing to think. Sailplanes and jets are very different.

The regular roam has a fairly large leading edge by design I assume to keep it back in the window for drift.
This is an incredible stupid way to solve this problem. You entirely ruin a kite so it can keep line tension. Then also you ruin it if it loses line tension...

So just because you can have a smaller diameter leading edge, doesn’t mean you should. It depends on how you want the kite to fly.
So the principles of flight are quite simple, high lift, low drag and weight. The larger tube diameter offers no benefit on any of those. So to declare that a tube size is for some benefit of flight is incredibly stupid, but then apparently so are most kite designers...hence we have chicken loops. Tubes however are structural and diameter is a structural principal.
I am surprised as yet why more elaborate bridling with an extremely thin tube hasn't been done. Ozone started with something towards that but not really explored fully. I guess having looked at the idiotic efforts to bridle tube kites this is beyond the stupid kite designer.

So Toby’s dream of a higher performance 20m lei is I think entirely achievable.
Toby's dream of a higher performing 20m KITE is already available. You just need a mind that is lets say a little more flexible than that which is susceptible to the standard marketing strategy the "brands" play.

If we go back 15 years ago I think we can get a good idea where aluula will have benefits and where there will need to be more work in design.
Definitely, 10g/m2 single skin kites that fly in half a knot. Such a kite would pratically never fall out of the air wave kiting, always flying to the wind or opposite. Or the same double skin foil kite, where it weighs so little now when the sun heats it it has positive static lift like a hotair balloon or the fabled "helium" kite.
Dont think material advances solely benefit tubes over foils. For certain tubes will get the most benefit. This is because lower weight to benefit is logarithmic, benefit gained decreases with more weight lost.
