Nope. I have two 50% SD 100% het purple sisters, and a mainland platinum female, all 2014's. The two SD's are about 9' long and their growth has slowed up noticeably over the last few months, the mainland has topped 12 feet and she's still putting on length (her dam is 20 feet). I don't expect the 50% SD girls to ever get over 10 feet.
One day when we get decent weather I should get all three out for a photo shoot.
