Best Cast On/Off for Scrunchable Scarf

I’ve decided to move beyond my basic dishcloth stitch teaching projects to making a scarf for my dad for Christmas.

As recommended here, I’ve decided on the Scrunchable Scarf because I think I can finish it in time. What would be the best cast on/off for this?

As I was looking at people’s pictures of this scarf it didn’t look like they did it in the standard LT cast on. Some of them seemed to match the actual knitting.

You could do the LT co and start with a WS row.
