Jacques Kallis started out with Lazer I think - only time I've ever seen one!
Funnily enough, my Dad used to import Lazer cricket bats, and Impact cricket bats, from Port Elizabeth in South Africa. They were made by Mick Bellingham, of Bellingham and Smith.
This was the Late naughties I believe in my Surrey schoolboy days!
Dad actually took calls from both Allan Donald and Jacques Kallis when they were in the UK! He said Kallis was extremely polite- which you can see in his interviews!
