My thought includes something from your name since you've taken Charlie's fine line and given it your own unique twist with this longbow.
I also thought it might be easiest for your customers to track if there was a name for each longbow riser style, then a common designation to show the upgrade levels.
For your the new longbow you have pictured: the Stalker "South Wind"- in Classic, Custom (or Deluxe), and Premium (or Safari, or Elite) grades.
For the more traditional style riser: the Stalker "South Breeze"- in the same three "grades."
The names promote the Stalker reputation, give YOU well-deserved recognition as the bowyer and designer, and give a warm, friendly feeling when I hear them.
I have a couple variations of these in mind, but that was what first "hit" for me...
Best wishes with your new product line
