My 2 1/2 yr old gelding I have now has Impressive bloodlines. But it is his Great x4 Grandfather. Every horse I have met that has Impressive lines have had such a wonderful all around temperment. With my gelding, I can't expect really to do gymkhana or any speed events, lol, just because he is sooo easy going, but I know he would maybe do good in halter if I ever got the nerve to show. If you want to know more information on "Impressive" himself here is some right here from www.allbreedpedigree.com
