Toe sides more difficult than heel sides... That's our alpine habits playing up. You're trying to initiate the turns like it was an alpine board. Which it is not.
I think the problem is that the skwal is percieved as an alpine board because it looks similar. Your body does not necessarely recognize it as something different and tries to adapt to it with a known technique. And that creates missunderstandings and errors. One should start from scratch and forget most of the alpine technique.
