The nice thing about Nitro boards is that they're big in EU but not as well known in the US (despite being based right here in the NW). You tend to be able to find them on deep discount at the end of the season or when buying previous season boards as you eluded to in your review. I had a Nitro Team Gullwing and NS SL-R at the same time, which were very similar, both fast but I did prefer the NS a bit more. Then again for what I paid, the NS was 3x more than the Nitro. I guess my takeaway on this review is that for this particular board, there are similar slightly better options for you, but then again if you compare prices, it would be hard to argue a similarly performing board for 40-60% off!
