Probably about 120km/h is my limit, I faced one of the top grade warehouse bowlers from our club, a Sri Lankan who was sending them down at a good pace - I would estimate about 120. I was pretty rattled - mostly just defence, defence - think I only hit about one attacking shot, a glance off the hips. I was too busy watching for the bouncer, one came through at head height and I practically fell over as I ducked under it. So - 120 is probably my limit now, I wouldn't want to face much faster. Bear in mind, I'm still in juniors cricket though.
