    <div>Hi,JoergS.First said my respect.<br>My English is very poor, maybe not clearly convey my meaning. Please forgive me.<br><br><br>My question is:<br><br>You use the flat rubber band, is theraband? 40 pounds tension, golden that kind of?<br>If not, it is special product?<br><br>Have you ever done a test. In the same tension, limiting tensile stress of the same length tubular rubber band and flat compared to the rubber band, and that a higher velocity to produce? Or the range longer?<br><br>Looking forward to your answer, thank you.<br>

    kook, I use Thera Band. There are different colors, I like the thickest (gold). It is a very good compromise between speed and life time. It is about 0,5mm thick.<br><br>You have to cut it into stripes. It is best to use my online calculator and read my manual, here:<br><br><a href="http://www.slingshotchannel.com/band_calc.html" target="_blank" rel="nofollow">www.slingshotchannel.com/band_calc.html</a><br><br>The speed is much higher than using tubular bands.

    <div>Thank you very much. I'll try yoga band.<br><br>But Thera Band's too expensive for me. In China, the length of 1.5 M Thera Band (golden) price is 20 euros. I only 150 euros a month. So, other brands can use?<br><br>If you can, please tell me Thera Band draw ratio. It is the limit how much? 4 times the length? I want to use other brands do a contrast. thank you!<img src="http://illiweb.com/fa/i/smiles/icon_cheers.png" alt="cheers" longdesc="28">

    Thera Band Gold can be stretched to 5,5 times the relaxed length. Thera Band Black and Blue even a bit further (up to 7 times). But the more you stretch, the faster it rips. <br><br>I tested other gymnastics/yoga bands, too, but all of them have been slow in comparison to Thera Band.

    <div>thank you. How many times usually shot, your Thera Band will fracture?<br><br>I used your calculator. Because of the shooting positions for the different, my right hand is put in the position of the corners of the mouth. So I draw length is 75 cm. This will affect the calculation result?<br><br>In addition, my English is so bad that "How far lesson 48 to stretch the bands?<br>How much tapering lesson 48? "Two options I didn't understand, so choose 5. It is the result of what influence?<br><br>"Band width at the fork is 3.44 cm.<br>Band width at the pouch is 1.97 cm."<br>This is tell me bands on both sides of the width?<br><br><br><br>Thanks.</div><div class="clear"></div><div class="signature_div">

    Thera Band Gold Bands with the stretch and tapering set to "5" will last about 120 to 130 shots, then they will tear at the pouch. They can be shortened several times, so you can get about 400 shots. <br><br>And yes, the calculator gives you the width for both sides, and the length. <br><br>Keep in mind these values may not be perfect for the yoga band you will use. You will have to experiment. <br><br>Note that you MUST use a roll cutter and a metal ruler, otherwise your bands will break very early. Scissors and sharp knives do NOT work.
