Looking to replace my 14m and 10m 2008 Best Nemi HP with 3 Rise kites.  Looking at getting the 13, 10 and 8.  Does anyone know if the 13m will have the same low-end as my 14m Nemi or should I be looking at the 15m?  As well, for a one bar solution, which bar is advised?

Replacing 2 kite with 3 is sybaritic and well worth it. First think which is the kite you need for the majority of your wind then work out from there. The 15 is superb in the light and the 12m razor is not far behind.  The bar has to be the big bar as the small kites can easily be slowed down on the rear line attachments
