No worries. You can learn to control your speed without putting your hands down though, I would try that first. Like I was saying just try some exagerated carves and when your in the apex push out really hard, it would resemble dynamic riding on a snowboard combined with a bit of a back foot kick, all the weight on your heel to grip your board. You do the same back on your toeside. Even if you can't get your board to slide, getting your wheels to grip like that will control your speed a bit.
