The three quickest bowlers I've personally had the misfortune of standing with my dick in hand 19m away from them in the nets;
Shane George,
Dennis Hickey,
Troy Corbett. George and Hickey roughly equal (145+) and skiddy (both guys roughly 5'7"). Corbett was reputedly mid 150's at his peak but I never saw him clocked to prove it, 6'3" ridiculous roaring movement away from the bat. All three far too quick than was necessary against me.
Hated facing Corbett the most even though he was the nicest bloke; being a leftie and moving the ball away from the bat, his line to me started a foot outside leg, right in my blind spot, so he rattled my ribs virtually every ball. Played some indoor with George a couple of years ago. At 38 with tight strings, busted shoulder and generally 3 sheets well before any of us rocked up to the game, was still terrifying.
