New dakota set up

I recently went to Ricks class and he suggested when I got home to shoot a 30 inch Axis 600 with a 165 grain head to shoot the Land Sharks 165gr. Well, I ordered some 600's and put the 160 grain head on them and they weigh 411 grains. The arrow I shot at the school was a Axis 340 with a 100 point head which weighed 419 grains. I also made a 30 inch Axis 400 with a 125 grain head that weighed 422 gains. This is how they shoot consistantly.

The 600's shoot really low and seem to drop, the 400's fly the best and are about 2 inches low. ( I could low my nock point to adjust) The 340's fly well also but not as stable. What arrow and head would you consider. Tim Antoine "The Night Stalker"

Hi, Tim
I am sending you a 35-55 gold-tip to shoot with the 165gr. It should be 420 grs. That what we should have done to start with. I was trying to get you the smaller diameter for better penetration.
