That looks good David - a nice classy easy-to-look-after style. I don't think anyone would ever twig that it is a piece.
I have bought European hair. It was quite expensive - I think it was a supplement of about $80 a few years back. The texture is different. I wouldn't say it was finer exactly, more that it felt silkier and less processed. But in the end I didn't consider it worth the extra money, so I haven't continued doing it, mainly because I am pretty happy with the quality and texture of the standard product.
Worth trying though, especially if you're rich!
