Radion TIR 120 degree optiks??

[Ryancw]

I'm torn on whether to try and get away with running two radions over my 60x20x18h and running the 120 degree lenses which claim to cover a 36x36" area at about 9" above tank and taking a hit on PAR or just sucking it up and running 3 with regular lenses... does anyone use the wide optics?

i figure since the tanks so shallow i should still get good PAR at the center of the fixture if i cheap out and don't pick up a 3rd fixture...

anybody?. i dont plan on keepin a ton of SPS but definately a few colonies. with the tank being shallow i should be fine?
