Rsky stopped manufacturing kites a few years ago, so Nirvanas are now only available on second hand market.
Benson superfly is already over 15 years old, but has all tricks pre loaded and a joy to fly every time. You can also look at
https://sportkitedesign.se/ as they have great kites and some that are less than 10 years old. In the US, there is
https://www.canvaskitedesigns.com/ which was created not long ago.
You wanted a list of 5 kites, here is mine: Superfly standard, Superfly UL, Superfly SUL, Superfly vented (Tim is still reluctant to build one) and SKD Mohawk standard
In the bag(s): R-sky, Benson, Prism, Revolution, Quadrifoil and a few more...
