All great questions. Sounds like you will narrow it all down to a great choice.
I picked up my Bredli from Nick Mutton last month. He is awesome! Was a big help and was willing to spend the time talking over the phone with me. He is a wealth of information and talked about all Carpets with me.
Mine is from Sept. 2015. Still looks like a baby to me. About 30 inches and skinny. 145 grams or so. I am 2 feedings in. I like being past whatever nippy phase they might go through due to having interested kids.
