I am looking for a pro-level bat ideally low-mid sweet spot and ideally suited for power hitting. Any advice or recommendations?
Get hold of a pro and try to buy his bat. May cost you a bit more and you may need some luck, but that will be an authentic "pro-level bat".
It's another story that you may not like the weight, balance, feel and pick-up because every person has a different muscle strength, and ligament flexibility.
Playing with Kohli's bat will not make you play like Kohli.
