Hi Marek

If we talk only about performances the Ultra Sonic 147 is really beter than iSonic 150 who didn't up date since 2 years. The US 147 have all the modification that we make on the iSonic 2011 + the extra length to get a very early planing.
In action the iSonic was particularly difficult with sail of 10m and over due to her short length, the US 147 handle 12 m without any problems, you can see the video on my Facebook.
If you hesitate between this boards, this possible but only for price, performances are much better in really all points.
Hope this help and you want more details just ask me
All the best
