well, it seems then that the general consensus is

1. not really for GI.
2. add to a few dull areas
3. every machine is going to have different needs, trial n error
4. a few well placed LED's is probably the go, versus adding many. (although reds n greens everywhere on a fishtales does look great i am told)

We need more before and after photos or videos, that would really be the best. Maybe post a few videos guys, espescially those who have done alot of led's to a machine.
