I have a 2015 filly, so also too early to draw too many conclusions about her, but I absolutely adore her and would love to breed to Sir G again. My girl is out of a Hanoverian mare whose breeding is Federweisser/Weltruhm. We ended up breeding to Sir G at the last minute, sort of “by accident”, and I’m so glad we did - that filly is leaving this farm over my dead body! 
She has had the most phenomenal temperament from day one. Very easy to handle, incredibly personable, but also super smart with a real personality, and is one of the boldest foals I’ve seen. Of the two previous offspring we’ve had out of this mare, one was a complete nightmare as a foal, and had a real temper (by RCMP stallion, Dubai). The second was very sweet but a bit shy/sensitive (by Sir Wanabi).
Thus far, she appears to be conformationally correct with three good gaits. She is lovely (although she is out of a mare who is quite typey herself). She is a tall filly, with more substance than the mare’s Sir Wanabi foal (now a coming 2 year old); probably similar in bone/substance to her Dubai foal. I am very pleased with her.
