Liquid Force Nirvana
I have had Hifis myself for years now and the Nirvana feels like the 2010 model which is great as the 2011 was a bit of a fall back in performance and not as solid or responsive (I stuck with my 2010 this year), so glad the centre strut is back for 2012! The battens in the wingtips do the job perfectly, keeping the kite rigid for quick response and solid shape, this is going to be particularly beneficial on the 7m as it will stop the super thin leading edge folding when looping and turning hard (had to pump the Hifis seriously hard to stop this). The 2nd and 4th strut have been moved closer to the wingtips to give a larger un-disturbed canopy section in the centre for a more efficient and powerful wing. Moving the struts closer to the wingtips also reduces any flutter and with full dacron from the final strut to LE the Nirvana has maxiumum response.
