I don't have any best kept secrets, I like to stick with the major names but if I had to pick one I would say the Piega line in particular the P10(more then 4k though) not many are famaliar with them but those who are know what I am talking about, one of the few lines I would ever think of replacing my avalons with(kharma's being one of the other brands I would consider though they are more well known)
