Hey Pirrad. I also started on a 12m Boxer. I then bought a 12m helix which I was happy with, until I tried a Bandit Dos. I had a few ongoing hassles with broken bridles and cheap pulleys with the naish. The F-One's build quality is much better, they're fairly bullet proof. Don't get me wrong, I'm not saying don't buy the helix, I was happy with it, I'm sure you would be too after the boxer. It's just that the Bandits have heaps more grunt and speed but still have excellent depower so their wind range is larger, IMO. Also, when you get the chance, pick up a smaller board. 145 would have been ideal to learn on, but at 90kg you could easily drop to a 133-136 size range and you'll find progression to tricks easier. Keep the 145 for those light wind days though
