even his float serve before is also good but this hybrid serve is really good but still inconsistent. He seem to go back to float serve when it’s crunch time
Kurkaev and Vlasov also changed from floating to at least a mix between jumping and floating serve this season. It might be Sammelvuo's direction.
But I like the fact of using the floating in crunch times or having an alternative to jumping serve, as it is very frustrating to see serve errors followed by errors, which is not that uncommon in certain teams/times or in the Russia NT.
