My technique is far from perfect. I do believe that part of the reason I can't get enough air is that I'm still learning. I'm not that desperate for a new board right now but it's the perfect opportunity for me to get one right now. I'm able to get a REALLY good deal on a K2 or Ride but it's only for a limited time. My brother doesn't have a board but wants to go with me this winter and I wanted to give him my current board. Thanks for the tips though. I wouldn't mind seeing more of these videos on technique if you know of any good ones.
Yea, I totally think you should go get a new board if you can get a good deal on them as you definitely have put some days on your current circa-2006 board. So definitely get a new board AND
spend some time/effort on learning better technique.
So, there are a lot of free videos out there, an I will link to a few of them right after this. Overall though I think the SnowboardAddiction videos are the currently the best there is, they are very well made, high quality instructional video with very good advice. At the moment you can pay around $27 for a yearly subscription where they put up videos like every month. Luckily for you, the included in the current set of videos available for you include the "Intermediate - Challenge" video (available until the end of this month, that's Nov 30th) which specifically covers popping, ollies, nollies, popping switch, basic rotations (180s) and butters... plus you will have access to any of the video they put up for the rest of the year. Currently you will also get Tuning, Pre-Season workout, Intermediate Basics which covers riding steeps and moguls (useful skills). I have no affiliation with SnowboardAddiction, but I really want to promote people that put out good honest products that I think will help a lot of people.
If you watched the videos of me... you can see I'm not a natural athlete - I break too much at the waist and in general look super stiff. However, I still think I'm not too bad a snowboard because
I spent a lot of time deliberately practicing my technique. So I really think spent a little bit of money on instruction will help you a lot (just trying to convince you that $27 isn't that much to spend).
Anyways, after my little rant about supporting small businesses... here are some free videos.
