What is different
Four things change between them. Pick one to look closer.
18K packs 18,000 carbon filaments into each thread against 3,000: a stiffer face that answers sooner on volleys. The Viper 3.1's 3K is a little softer and gives you more time when you are late.
Edge: the Hack 04, for precision
* The feel starts from the core's rated hardness (estimated from the core material where there is no rating), then the face: carbon 12K and up is firmer, fibreglass softer.
About the same weight: 370 g and 365 to 375 g.
No edge either way
The balance point is not listed for both.
No edge either way
* Drawn to scale: a 455 mm racket in its shape's outline (traced from a real racket of that shape), with the balance point the shops list marked on it. Real rackets vary by a few millimetres.
