ET's website lists the XP-G2 R4 and XM-L2 T6 as the 2013 neutral choices. I have a nailbender P60 drop-in with the XM-L2 T6 5000k emitter and it's become my favorite neutral tint. Nichia's 219 rose tint always bothered me and was a little to warm for my taste but the T6 binned XM-L2 5000k is a slightly creamy vanilla tint I love...and extremely bright.
