Thanks both! I wrote the length wrong. It is the Skywalker 131x40 I mean. I already ordered the 135x47,5 Skywalker. But as smaller board for my 90 kg. I consider either Nobile 555 135x40 og Skywalker 131x40 A dealer just told me the difference is that the Nobile has concave and the Skywalker does no...
