This was Saurav Ganguly's personal bat that I was lucky to acquire. It was stickerd as SS Ton LE (old black and gold stickers).
Before me even telling anyone about the history of the bat, many folks praised it's shape, balance and pickup. A few even requested to bat with it in a match.
I sent it to UK for rehandlig, and obviously it got lost in UK customs. Ouch !!!!!
I don't think any bat that I have ever used can come close to it. I so dearly miss it.
But my second best would be Redback Allegiance. This was Gary's personal bat that he had used in a couple of games. At 2.7ish, it was a delight.
A good friend snatched it off of me but I became a Redback fan since then.
Couple of years ago I acquired a personal bat from Misbah ul Haq. It's stickerd as CA 10000 LE. Grains and cosmetics are supreme. I haven't got a chance to play with it. It just sits in my closet.
