Would you buy a horse that had Impressive in it's bloodlines?

you always have to be picky in bloodlines: that can make or break a horse. i am not a QH person, but i have heard of Impressive,and Zippo Pine Bar. I would definitely buy an Impressive. My brother was a big QH show person (he went to the World) and I am a Show Jumper myself, and i know how important bloodlines are. I know that Impressive is prone to the HYPP, but I think that can be prevented, no? but any way, i think i answered your Q. so good luck.
