I think Tendulkar used heavy bats. So 3 lbs for this bat seems about what would it take.
Personally, I think it looks bottom heavy, and will need getting used to.
A 3 lbs bat, straight off the shelf, is not for everyone.
Pick-up, feel and balance of a bat plays a much, much bigger role in delivering performance of a batsman rather than the profile shape, willow grade, manufacturer, or stickers on the bat.
A $50 grade 3 bat with the right pickup, feel and balnce that suits YOUR muscle strength, ligament movements and hand-eye coordination, may help you score more runs in stylish play than playing with a $10,000 bought, Kohli's personal bat that does not suit you.
If you think Tendulkar's profile or his personal bat will make you play better then perhaps you are a novice cricketer.
I think there is a good chance that petty soon you will be done with this bat and will try to get rid of it but perhaps you won't be able the recoup your moolah, which is daily norm of the industry.
