oh they are starting to reuse kite names now as they reached the end of the list? Wipika Apm'ed anyone. Loved that kite - until I ripped it in half mid air on a huge jump .
Funny you should mention that. I owned a Wipika Amp - I thought it was a terrible kite. I had been riding Airblasts & then bought a 12m Amp. I found it did not de-power like the Airblasts. It was way more fancy in materials & finish than the Airblast, with an elaborate bag & bar ... but I didn't like the way it flew at all.
Looking at the shapes, the C4 looks more extreme to me, and I didn't think it was that extreme for a C-kite to be honest. I think it's more of an image thing, just like when the Catalyst turned into the Enduro, and Ruben can help there.
I always take the marketing stories with a grain of salt.
