I'm not really sure if I'm skiing correctly because I keep bouncing downhill with the space bar held pushed instead of moving smoothly speeding foreword. To me It doesn't look like I'm skiing very well. My technique is jet pack up hill and hold down space downhill. Is this the correct way of skiing ?
That's what skiing is, yes, though you'll find if you pick up enough speed it won't feel like you're bouncing.
I think there may be some videos with tips on technique and routes you can watch, but the general principle is that while you're jumping you won't be slowed by surface friction (depending on the mod).
I could only find one video on YouTube and it's a video on capping. He did go over the basics of skiing and I think I need to work on my jetting timing a little.
