These are my personal, as well as many, favorite frames on the market. They were the first UFS in 1997 and remain on top. They are getting some competition from Ground Control and a few others.
It's all a matter of what feels best to you. These slide at top of the line with Ground Control. Try out different brands. I'm definitely glad I got these. Some people don't like them as much as others, its all about personal preference.
