Varied Light Angles= Higher Plant Exposure?

Hey guys. I recently set up a 4x4 grow room and was wondering, would it be better to use my 1000wMH or my 600wHPS/MH, and my 2 175w HPS/MH. I was thinking that if i put the 600 directly over the lights, with the 175's mounted at a 45 degree angle on the top of the wall, It would increase light exposure to lower parts of the plant?
Any thoughts?

The 1000 will give you heavy canopy penetration giving you a good solid end result with the lower buds filling out more. But I know that it is argued that you can get tighter buds with a 600. Just my .02

Happy growing

thx DR. M! I guess ill see how it goes
