When the exact guess for Longest Six hitter for IPL 6 is asked, it means that only one cricketer name should have come from each individual. :)
Don't tell 4-5 names and who are the good contenders.
IPL is now in it's 6th season and there are lots of players with potentials for hitting long sixes.
Request you to provide just one name who you think will surely hit the longest six in IPL 6 and see whether your guess is really correct or not. :)
