OPE vs. Envy Orange

[LoudProudNPunk]

what are the main differences between the two? i cant really find any other than the extreme price range.

The biggest difference I've seen is that OPE's (which are arguably true RPE's under lower K lighting in most cases) have the dark circular area around the mouth, where Envy Orange are solid orange all the way up to the mouth. All reports from those with Envy's are that the growth rate is almost zero, fwiw. I've never seen a side by side of true RPE's, OPE's, and Envy's from the same system to see the actual differences...
