Just about any fixed head will be fine. I pull 60# with a 29" DL and I shoot G5 Strikers and they have treated me very well. Easy to tune and stupid sharp. As was said before though, a well tuned bow and you can shoot just about anything. I would stay away from the large cut mechanicals, I don't know how fast your bow is but you may be on the low side for some of the mechanicals out there. If mechanical is the route you want to take it's hard to beat the Rocket/Trophy Ridge Steelhead in the penetration category.
