Hankook Ventus V12… Experiences sought (wet, wear, saw tooth)

Hello forum, since my Michelin (225/50 R17) on my Astra (J, SportsTourer 160 PS CDTI) saw teeth I wanted to raise new Pneus. Actually it should be the Nokia Z G2. But now I have come across the Hankook, who get good reviews from all sides. I am not a very sporty driver, but value grip (especially at the 350 NM), good properties in wetness and wear. Unfortunately I have neither in the search, nor in tests an objective evaluation of the Langlebi In my view, the profile does not allow for this, since there are no profile blocks available. How are the wet/aquaplaning properties really in wet weather? In the tests there are times like this and so. Can enough water be displaced despite the continuous profile flank? On the subject of durability: Can someone say something concrete? Is it worth ~20% more for Pirelli or Michelin? to admit? Keep the then 20% longer (both brands should be quite low in wear…) Many greetings, Thomas
