I agree with KBI Prez, try locating your nock point slightly high so your arrow leaves the bow slightly nock high and point down. Also don't forget that when the arrow enters the water it will appear as though it is moving shallower and planing up but in fact it is not as much as you think because the arrow will appear more shallow due to the refractive difference of water and air, ie light travels faster in air than water. In Aim Low's first production, they make a nice slow motion shot on a large grass carp and it really illustrates what I'm talking about nicely. This is of course the same phenomena when the fish appears more shallow than it really is and I shoot over them all night.[:@]
