I know nothing about Keep the Faith but Danewin sounds like he's from Danehill lines. My filly has Danehill lines too!
What I have found with my girl is that she is VERY sensitive and can be VERY hot but she is incredibly sweet, quiet and gentle. She's just explosive when she's scared. I know a couple from the same lines that are the same but I also know several that DON'T have the explosiveness, sensitivity or fizzy behaviour. It seems to depend on what the bloodline is bred to. My girl is from a Laranto mare and I know of one from the same sire and damsire that needs an ounce of lead between the eyes [aggressive chronic rearer] but I used to work for a lady who had a Danehill stallion and that stallion was LOVELY. Easy to handle and just lovely. One of his foals is the same as Magic and the other one that I've met is just completely the opposite. A bit thick but an absolute puppydog. Those two are full siblings I think and couldn't be much more different temperament-wise if they tried, but physically they could be identical twins! Same body shape, same colour, same markings, everything.
The Danehill line tends to stamp with either brown or chestnut, a pretty face, and reasonably good conformation. My filly has small but well-formed, hard feet. I've noticed they tend to be between 15.2 and 16.1hh, the stallion was 17.2 but he was the exception!
