    So I was able to get my hands on some new TB Blue and TB Black. Since the calculator is only for gold, I was wondering how/if I can compensate the same measurements with multiple layers and exactly how many; or in what other ways can i be compensating band without losing so much power.<br><br>In other words, how should I make bands out of TB Blue and TB Black.<br><br>"Thanks and bye bye." -Jörg

    Blue is three times weaker than Gold, Black is 2,3 times weaker than gold. <br><br>So you simply have to multiply the calc results by three for TB Blue and by 2,3 for TB Black. <br><br>I usually fold the thin blue and black bands, cutting them into stripes is just to tedious as you need so many. <br><br>Jörg

    <div>Thank you so much Jörg, so your saying i need to multiply the measurements of the TB by 3? ie. 2 inch @ fork would be 6 inch? <br><br>Could I just stack 3 layers on each of blue on each side?<br><br>Thank you so much btw, very helpful and useful stuff. <br><br>"Thanks and bye bye." -Jörg</div><div class="clear"></div><div class="signature_div">

    <span class="postbody"><br><br>Yes, 2" becomes 6".<br><br>You can certainly use three layers of blue when the calc says one for gold, but as I said I leave the blue and black stuff in one layer and simply fold it lengthwise. It is too much work otherwise, and there is no difference in performance.</span>

    <span class="postbody"><br><br>if I transfer this to your calculator this means that if the result is: I need two therabands gold per side with 2cm at the fork and 1,5cm at the pouch I can cut one band with 4 cm at the fork and 3 cm at the pouch per side<br><br><img src="http://illiweb.com/fa/i/smiles/icon_rolleyes.gif" alt="Rolling Eyes" longdesc="14"> my question is - why did you calculate with multiple layers and based on what criterias?</span>

    Thera Gold is pretty stiff, and will bunch up when you make it too wide. So as soon as it exceeds a certain width (probably around 4,5 cm), it is better to use another layer.<br><br>The thinner black and blue are much more flexible and layers aren't needed.

    Ah, that sounds really logical. Thanks for the clarification Jörg. <img src="http://illiweb.com/fa/i/smiles/icon_exclaim.gif" alt="Exclamation" longdesc="16">

    I like both these elastics. They're both fickle but give very efficient return when tuned properly. I like them more than TBG, really they well outperform it if only for a short life. If it's all about the shot I'd take either one over gold every time. I don't know if they work as well with heavy stuff, though.

    As soon as you exceed 16mm steel, the difference is minor. Anything below 13mm steel, the advantage is notcieable.

    How about 14mm lead?

    14mm lead weighs the same as 16mm steel. TB blue/black will be slightly faster (not very much). Not really worth the efforts.

    If you are folding over the black/bands, are you saying that you don't bother with any tapering? Sorry to seem so dense. It's late in the day and my brain is running on half power.
