a topic hard to be discussed, you have to experience it...
So you should test ride it not buy something blindly.
Personally I do not get along well with this lifted bottom bracket thing. To have a similar pedaling position for riding efficiently longer distances, you have to lift than similarly the saddle, and I do have simply the feeling not sitting centered at bike any longer, but rather just on top of it.
It may still make sense for Trial usage etc. just not for me and my riding style.
Sure, I do like a bit those new and modern Geometries with rather a few centimeters BB-drop, which came with the move to 29ers, but you can see those things nowadays even with for instance kids bikes in small wheel diameters too.
This gives you simply the feeling of being part of the bike.
