i pretty much pick up the bat towards second slip but like to think it comes down straight, if i've not got my timing right or the bowling is a little quicker than i can get in line with then i'll pick up the bat straighter, but maybe being a left hander who bats right handed like Michael Clarke makes it easier for me ot do this as my top hand is the stronger hand, i thnk this also helps me cut the ball well as i'm more focused where my top hand and the the secondary tohught is to get some bottom hand into power it off, but by the same token, it's less natural for me to get the ball airborne
