Pivot is fantastic for foiling but like others have stated above, if you really want to get low end, you have to use a foil kite with a hydrofoil so that might be a good reason to have a mixed quiver. Hard to beat a 12m soul for low end hydrofoiling. So it does depend on how low you want to go. If you get to light enough wind speeds you need to have a foil kite, because at the lowest wind range tube kites just fall out of the sky. i'm always on a mixed quiver for cost reasons, I just buy what's available and hate it. Liquid force, slingshot, wainman, duotone, naish, pansh, ozone, C kites, hybrids, regular bow kites, foil kites I think I have 15 kites now most of them old a few that are brand new but I want to get rid of all of them and just have 4 kites. Waiting for next year, it's slow in the winter, so harder to unload my old stuff. It's way better to have just a one kind of kite and keep them new, maybe two types of kite if you need one for wakestyle or hydrofoiling.
I would have put the emphasis on the word "NEED" in the above statement.
Just like 2016-2019 Rally the Pivot is amazing universal kite. Boosts great, drifts well and turns fast. Less bar pressure than Rally but I can’t stand unnecessary complexity of Pivot’s squid inflation system
