I've used both BB7 and hope's and to be honest if you look after them there's not that much difference in them
But i do love my hopes a lot more, I don't have to mess about with it half as much as i did with my bb7.
Hope are also amazing with Warranty if anything did go wrong too.
Both BB7's and Hope have there pro's and cons though.
Edit: I used the new style BB7 and i'm using some fairly old mono trial calipers and the new tech leavers on my hopes.
