Taking all the good ideas of each other well know brand designers of Vangard style, i 've drawn what i called as the MIX.
Is a 6'9" 27" 80 liters, with a planning area made of mono concave with double convergent channels, depress outline to enhance rail to rail transition from the outline and increasing stand up balance , as well as and many other shaping components.

Want a drag on it

Yes! I can be able to roll it up a bit wider for you
Are you ready to stand it at 90liters
