Most cut on contact style heads will do Ok for plains game as long as you don't encounter any big bones. Still, it is good to have some insurance with a strong, quality head. Blood trails aren't really an issue as the trackers don't usually need them. You've just gotta get it killed! I used grizzlies last time...will be using Eclipse this trip. You wouldn't go wrong with modified tip Wensel Woodsmans, STOS, silver flames....or probably a big Magnus 1 (I hate to agree with Pauly B). You might consider pushing your arrow weight up just a tad, though. I would feel more comfortable with something in the 6 or 700's when things go "less than perfect," and bone is encountered. Best of luck. Brady
