I just bought both LED OCD and GI OCD for my Monster Bash tune-up. Honestly, its had LEDs in it so long, I don't recall if there is any fading in the GI or controlled boards, so I'm curious what kind of difference I'll see. Strobing is pretty bad and the LEDs are kinda harsh so OCD should be able to help me with that.

Sorry for the 3 month late reply! LED OCD is fantastic in Monster Bash. Well worth the money and indeed I had forgotten how much better the incandescent lighting behavior looks. Now its the best of both worlds with the deep, vibrant LED colors and soft transitions of incandescent. Love it.
