Ovtcharov alc I used quite some time allready with different rubber combinations (pk 50 both sides, Dignics 09c both sides or Dignics 05/80 backhand, Glayzer09/Glayzer, LGY I like too. Both are quite good.
Today I did an standard irregular exercise with Ovtcharov alc for some rubber testing: coach was serving long underspin randomly to backhand/middle/forehand side - l loop it and he keep blocking randomly to different parts of the table. After the practice he was telling me that today after I keep so many balls back and with quality on irregular and other exercises - it was my best performance in all time in his opinion. And my coach is rarely telling me that I good in something.
But I also did a lot of training in past three or four months (3-4 hours almost everyday, sometimes two training a day) - but whatever Ovtcharov alc is very suitable blade as many are. It is hard and kinda thicker with larger head in comparison with LGY or Viscaria SALC. Depends on your needs and preferable rubbers 🤓
