#1 When they say strong willed it worries me... Does that mean he is strong willed in things going HIS way? Idk, They didn't give much of a description.
#2 I think he's exactly what you are looking for! But i'd want to see him in motion before I make any final decisions. I do like him though
#3 You can't really tell a whole lot by the add, but I think he's worth seeing in person!
#4 I think he would be an excellent show option! He's pretty too, but you should ride him before you make decisions.
#5 He's cute, maybe email for more info though. The add wasn't very detailed
Personally I like #2 the most, then #4, then #5, then #1, then #3
