OMH,

It would be much easier to make a recommendation if we had slightly more info. The speed of your current setup being very important as well as rough idea as to your arrow weight. With these two figures you can determine your Kinetic Energy and then a recommendation becomes much easier.

Some of the info in question can be found at www.bowjackson.com. He has arrow weight charts and a KE calculator.

If you want a wild guess then I would probably say you are borderline for Hammerhead usage. The reason being your draw weight. Generally speaking, a 10 lb reduction in draw weight equates to roughly 18 fps in arrow speed. 18 fps can have a huge impact on a person's KE numbers and high KE numbers are definitely needed with a large cutting diameter head like the Hammerhead.

But then again you probably have plenty of KE for the Steelheads considering the more compact overall design and smaller cutting diameter.

One suggestion...you might want to try the Sidewinders before moving "up" to the Hammerheads. The Sidewinders have a 1.5 inch cutting diameter but more of the overall shape of the Hammerheads. A good compromise of characteristics between the two heads you mentioned.

Hope this helps.
