I like in all it's forms, I love the way you can have basically the same rules but just change the number of overs then the entire game changes - it's fascinating.
I love going to a T20 on a Friday night after work for night out. I love spending the day at a Test and wondering which way it will go, but then I'll be equally happy at a 50 over game seeing it though to it's conclusion. As to Test Match Special on the radio -
Not sure about The 100, I think the efforts would have been better promoting the T20 game, if they could have used that money to get the T20 on free to air, I'm sure that would have worked wonders.
