If you are needing something bigger than a 6.0, think the Freek 6.3 would be a wise choice

You get going in 10 kts with a 5.2? No doubt a technique thing but the other week I was struggling to get going in 12-15 kts (as measured by Seabreeze) with a 5.3 wave sail on a 1500cm2 med aspect foil. How much does a foil specific sail make that much of a difference?
Technique definitely helps, as soon as there is enough pressure in the sail to put pressure through back foot to the foil. Bare away with short pumps on sail and back foot simultaneously to build speed works for me.
Foil specific sail definitely makes a difference, before I had foil freeks I had Naish force fives. I didn't have a hope with a 5.7 to get up in the same wind. Foil freeks and freeks are so light and fill out very easily especially when you are conservative with downhaul and outhaul.
I haven't used other brands but sure there are other sails that will give similar results.
