Awwwww shucks Jason....... Thanks for the compliments.......now quit sucking up.

Brodie, the HCA Four Runner (especially the MX-1 cam) is a pretty fast bow in its own right......And at 65# and 29.5" draw you have plenty of energy to shoot a good majority of the broadheads on the market.

KE (Kinetic Energy) is a very important component of penetration and proper broadhead choice......you should have ample kinetic energy.

Since you are a beginner, I am torn as to what I should recommend. A proper arrow/bow tune is important to get the most out of any broadhead, however it is even more important with respect to Fixed blade broadheads........I could go the easy route and say shoot a certain good mechanical broadhead which flies like a target point, but I'm going to go the other way.
If you want to learn how to tune arrows for broadhead flight, I am going to recommend a fixed style head .....the basics that you will learn by tuning fixed blade broadheads will give you the foundation for understanding the "How's and Why's" of bow and arrow tuning.
You have an entire off season to play, and you are going to learn a TON of information. Todays magazines and internet etc make the learning curve a lot quicker than even when I started bowhunting almost 20 years ago.

The 2 that Buck Magnet suggested, in the Muzzy 100gr and the NAP 100gr Thundehead probably account for more game taken than any other heads made.
You will want 2 sets of blades as well......a practice set and a hunting set that only sees the light of day when you are hunting.
But don't sweat the broadhead stuff just yet, get to know your bow in and out, what it can do, your abilities how it works, why it works etc etc.

Here is a link to a great website that has arrow weight and KE calculators and a ton of other good stuff and links:

Play around on there a bit, and stay with us on this forum until next season......I don't want to get more in depth than that right now because the season is so far away. Just shoot the bow a lot, practice as much as you can.
All the info you need you will pick up along the way, and hopefully by next season you'll be ready to rock.
