I have the VXR v2 18m, and it has been my favourite kite (until I got my new Vantage18). I cannot comment about the 17 but can say that I found each of the sizes (I have 8. 10, 13 and 18) to be good kites.
I am a very keen racer and have been very pleased with the kites as race kites. Not sure about for freestyle - I am sure there are kites that would be better for that. But a 17 would certainly get you out a lot more than a dedicated freestyle kite.
The kites are stable, user friendly and quick around the course. Relaunch in light wind takes a bit of practice and technique, but any race kite has similar challenges. The secret is not to drop it in the water

I had a great session today in 7 to 10 knots, with the Perth Swan river all to myself. If you want to get into racing, I reckon you can't go wrong with this kite.
