Luminarc Stealth VS LumenMax Elite

[Trigger]

So I finally ordered my tank (30X30X18 rimless with starphire on 3 sides) and I'm trying to figure out which reflector will suit me best. I've narrowed my choices down to the Luminarc Stealth DE or the LumenMax Elite DE. I have read that the arc has a more "spotlight" effect while the max is a more spread out light. For something shallow and only 30" across something tells me that the Luminarc might be a better choice.

I'll be using a phoenix 14K 250W DE bulb and want to keep primarily SPS/LPS
