Can someone please describe the differences between the various pastel lines? (e.g., What's the difference between Graziani, Bell and NERD pastels?) Did each of these lines originally come from a specific wild caught mutation that were subsequently proven out, or did they result from cross breeding other lines to create a unique variation of a proven line? Also, do certain lines command higher premium than others, or are price premiums tied to how specific animals look?
Just curious. I see everyone touting specific lines and was wondering if certain lines functioned as premium brand names (kinda like Porsche vs. Ford).
Thanks!
Bruce
