Three rackets called Viper doing three completely different jobs. Also the worst value scores in our database.
The Viper name covers the whole spectrum. The Technical Viper holds our power record at 9.7, with five sources agreeing within 0.6 of each other — the tightest consensus on any dimension we have recorded. The Air Viper is the lighter, faster take at 9.0 power. The Counter Viper goes the other way entirely: 9.2 control, built to absorb pace and redirect it.
All three share the three-layer X-EVA core and the Vibrasorb damping system. The difference is the head shape and the balance, and it changes everything about who the racket suits.

Value is where Babolat loses ground, and it is not close. The three Vipers score 7.5, 7.4 and 6.5 on value — the three lowest figures in the database. List prices run 320 to 349 USD, and Amazon UK pricing swings wildly across the range and across generations. The Technical Viper 2.5 sits around £123 while the 3.0 asks £291 for the same nameplate.
