This is one of many things I have toyed with in the back of my mind..
HYPP or not? Hmmm.. You know, to be honest, for me, it would be case by case.
Impressive really did set the bar, and with halter none the less, which is one of many things I look for when it comes to standing. I really can't say yes or no. I personally know that to reproduce anything with this would not help the issue of eliminating that flaw, but on the other hand what I could end up with on a positive end, and not mind taking care of is conflicting...
I will let you know when I can make up my mind. But this is a very good question!
