Elton has conspicuously used his own sideburns since he started wearing, but his pieces have greatly improved over the years. Barring some new technology, they probably aren't going to look much better than they do currently.
Yes, it looks good. And like someone said, TL pieces can look just as good. However, I'm sure EJ's piece is made of virgin european hair and not remy indian. other than that it's probably the same deal (sfs base etc)
