Hi all,
I have had a chance to ride the 2013 Ozone Catalyst 12m now twice, for about 45 mins the 1st time in winds ranging from 14 -18 knots and 1 hour the 2nd time in winds ranging from 16 -21 knots. I cannot give a thorough review yet but so far my impressions are very good compared to previous iterations of the catalyst, which has been a favourite kite of mine in the past.
I would say that this years model is a great evolution of Ozones "do it all" model. It appears to have picked up some beneficial design characteristics from the Reo and C4 that have been incorporated into its new more compact C shape. This years Catalyst is as smooth as ever, maybe more so, and its overall user friendliness, that has always made it an awesome kite for those of us who love to jump while riding waves and still throw in a few tricks here and there has definitely been improved. It is a little more dynamic than previous years, the 12m's turning is a little crisper and I would say a little faster than before. Jumps were very good for the conditions with good pop, height and smooth glide. I think on first impressions it is going to be better in the waves this year too, not that it was not good in the past, but it drifts a little better than previous years and the turning is direct and fast (not reo fast but pretty good). I think upwind is still excellent for this type of kite and the bottom end appeared good in the lighter winds I had it out in the 1st time. I am 94kg riding a 136 Twin tip by the way. I can't wait to try out the new 8m in 30 knots!! I will give you an update when I have!

Here are a few pics I took of the 8m on the lawn.
