Its amazing what a difference it makes when you get it right though isn't it.

Yes it is.
It can be a very fine balance to get it perfect.

Even after I think I have the game PERFECT I still occasionally just try ONE bulb change in one spot.
EG - Nino's T3 looks awesome how he did the LED's- but yesterday I got to the FINAL BATTLE and the PF insert for that sits amongst the PF inserts for the other modes - they are all lit in white. So I am going to change the FINAL BATTLE LED to either another colour OR to a colour changer - just to see how it looks as I think the FINAL BATTLE needs to be highlighted.

Sometimes little things like this can make a great looking game just that LITTLE BIT better.
Yes I am a little pedantic
