Interesting about the 20oz soda bottle reference. According to that my early 2011 lipstick sunglow would easily be breed able next season. That sounds crazy to me. I feel like she needs to be much thicker to breed!
I have a 2012 female motley that is a tad over 3 foot, but I think she is a slower grower, compared to friends of mine who have 2012s almost a whole foot longer and twice as thick!
