I do the same, using the Howard Hill 'split vision' indirect gap on the longer stuff and instinctive on the close shots. But I've learned in the past year that I also visualize the trajectory of the arrow. In 3D tournaments I've gotten into situations where I knew if I split THAT weed or clipped off THAT leaf, that the arrow would center the 10 ring, and it happened. Well, more often than not anyway.
