Number of G4 pros for sps tank

[ThaBeast]

Pretty sure I'm going to order G4 pros for my display tank. Will be predominantly SPS, 96x33wx29h. Should I run six units perpendicular to the front pane or eight units in 2 rows of four parallel to the front pane? Switching from a pair of 10x54w power modules due to heat

I'd personally run 8 end to end, 2 rows deep. Better coverage. I run 4 in parallel on my 48x24x30.
