I accept that these photos are not great. Bat in 1st and 2nd photo is same and is Shane Watson shape. Surinder chose this bat for me and said ignore the grains but trust me it has great performance. I went with that and it was a great bat but I damaged its toe and was replaced free of cost with another bat in last photo that is dhoni shape. Even though it was my own fault.
I don't weigh bats anymore so don't ask me about weight as I don't know. Purely go for feels these days. I ask RS for a well balanced bat regardless of weight I trust them on this and they delivered everytime.
3rd photo is bat for a teammate who asked for low middle but light weight. it looks big but feels balanced and light so he be happy with it for sure.
Bat in 5th photo is again Dhoni shape and on heavier side as the owner is a strong lad and likes heavy bats.
I am going for performance here so grade are irrelevant for me and it depends on your budget.
I spent few hours in office with Surinder came to know about their history learnt few other things regarding bats pads gloves etc. He gave me good deal on my personal bats, custom made pads (black inside white outside).
