The spitfires are excellent mechanical broadheads. At 60lbs your probably right at the edge of what I feel is ideal to consistantly get pass throughs with most shots.

The razorbacks are decent heads, not as sharp as most NAP heads, and you can't replace the bleeder blades.

The crimson talon Xt is actually a very good head. They have improved this head over the last 5 years or so and now I feel it's one of the better fixed blades on the market. They could still be sharper, but they are plenty tough now. They will tear up a broadhead target quicker than most heads though, but the upside is that the same damage done to the target is also done to the game.
