So I built a RI special gun and finally got to use it today, it's a 47" mid handle. It has the band stretch of a 100cm euro, but the length of a 75cm from the handle to the tip. The spear has super short overhang because it's designed for shorter ranges and maneuverability.
I will add a reel tomorrow when I get them in from a special courier in FL. Hopefully my dyneema arrives soon after. I will go over the specs of the gun and in detail later. Today, I just needed it to shoot. Water was 50 degrees F. I scrounged up some old, heavily used bands to make it work. It shot really well with minimal recoil as there is so much wood (I want to trim some out to reduce it, actually)
Lastly, I named it "White Chin" for the primary target, Tautog or Blackfish, also called white chins (prominent when they get big). I will fry these up tonight and have noodles.
