2smb frosted daylight is the ONLY LED anyone should be using for all GI's. 1smb for backbox GI's to reduce glare. And even with that, I'd suggest leaving 82% of the sockets empty. Cuts down on glare dramatically and still looks great.

sunlight is what i use. Warm is great too. You really can't go wrong either way. If you want a more futuristic look with cool pallet games, use Cool White. Only a few games look good with cool white. DM looks fantastic with it, as does JD. I used Cool white on the purple side of my TF and warm white on the red side. That's as extreme as anyone should get when playing around with GI sockets.

I would not use 2 smb for inserts or backbox. Too bright. Use the 1 smbs. Or you can match colors with the color of the insert, as long as the insert isn't printed with screened with multicolored printing.
