    When I was anchoring on my jawbone I was using 0.08mm thick bands tapered 25mm to 22mm , with a 6 3/8" active band length.

    Now that I'm shooting half butterfly and loving it, my active band length is 9 1/4". I'm looking for power over speed, maybe a happy medium between them both. But I'm wanting to get the most power as I can out of my setup.

    Now my question, should I stick with the same band thickness and taper, or would there be a better combination? I'm open to any suggestions, thanks!

      I think you will find speed is what you are looking for. Actually thinner bands move quicker. Force = speed x ammo weight

      thicker latex does not necessarily mean more energy into the ammo. You need to do some testing to get your best combination.

      What kind of testing do you recommend? I know a chronograph will give me the speed of the ammo, but how is the best way to determine the energy the ammo is producing?

      When I get home to my PC, I can get you more info. Most chrony’s have apps that will calculate energy of each shot.

      I have a spreadsheet that will do the same.

      Power for what? Hunting? Can smashing? Ammo?
      I agree with the above statement, when shooting half or full butta, what you want is speed!!! I qould go witha thinner band material and a bit more tapper, i like .065 tgick 3/4 to 5/8
      I am sure you will find a suitable set up. Its half the fun :D

      Here is Nathan's take on latex thickness.

      Once you go thin, you'll be spoiled with the easier pull weight and faster shots.

      So, assuming you still shoot 7/16 steel and big lead through a TTF slingshot, my vote is to keep using your .80, and sample something in the .55 to .60 range. Your current taper seems to be working, so keep it. You can use it for a starting place with the thinner latex, too, although you may widen the cut some if you want more performance.
      Kinetic Energy is calculated as .5 times the Mass(weight) times the velocity squared. So increases in either the ammo weight or speed increase the energy. There are charts on the interwebs.
