I use eggcrate, it works well for larger fish and does not significantly reduce light levels. I have great growth and color with many higher light plants, ie.: Pogostemon stellatus 'Broad Leaf', Limnophila aromatica and Ludwigia sp. 'Guinea' (75g @ 192w).
I did still loose several skittish Danio choprae to jumping. I don't think the Danios liked being in with my spastic Congo tetras. The Congos go into overdrive when competing during breeding (almost daily); and they're twice as bad at dinnertime! I never lost any Hengel's rasboras to jumping though, so it definately depends on the fish as well.
