There have been a number of discussion in the past that make it clear that this is not necessarily a stright forward question because your palm (and the back of your hand) are curved when you're gripping the club. In addition Scott has a procedure called 'balancing' which you use to set your grip on the club and he teaches that the position relative to your grip to hit a particular shot (say - straight) may vary from day to day.
There is in addition a finer point about lead wrist position however in normal golf language my grip would be considered 'neutral'.
