In all seriousness, 20/4 or 18/6 do have advantages. One, they will save a little on your electricity bill. Two, like previously stated, it will allow your light's ballast to cool. Also, if you can afford a few cfl's for veg you will be able to really save on your bill and ultimately make your hps last longer. Overall, 175 hps puts out over 17k lumens so of course it will work just fine.
