I have TEK II reflectors and am impressed with the amount of light they bounce back (especially when they were new). They're a few years old now and have some discoloration/staining but still perform pretty well. I've heard that the Icecap reflectors don't stain as quickly/easily but I've never owned one.
+1 to ReeferRobs suggestion.
HTH,
Tom
Tom have you tried cleaning your reflectors with Vinegar or Alcohol?
