Is it me or my board?

Need some advice… First up, here’s a bit of info about me: I’m a female rider, intermediate, confident on most blue runs and some black runs if snow conditions are good. I currently ride a Capita Defenders of Awesome (2014) board.

I’m having a few problems that I just can’t seem to overcome and I don’t know if it’s me or my board:

- I can’t seem to gain much control on hard pack/icy runs. The board just feels like it wants to run out of control.

- The board feels quite slow to turn, especially if I gain a bit of speed. Sometimes I find myself stuck on an edge and it feels like the board doesn’t want to turn, then if I try to force it that’s when I crash. It doesn’t feel very “agile”, which makes it really difficult to pick a line when there are moguls.

Do you think I need to work on my skills, or does it seem like the board isn’t suitable for me? Or perhaps the board needs tuning?

Here are the board specs:
