    How is your temperature, this could make a difference. Also pouch weight and size can affect speed.

    To get 120mps you need a very HOT day 35°C+ and as Onnod and Thordsen said a very light weight pouch and ties ... anyway 70 to75 mps is a common decent speed for a ss ...

    <div>Acctually more rubber isn`t always = more speed.<br>more power but not more speed! <br><br>That´s what i´ve learnd with more rubber you can shot heavyer ammo but with<br>the same bandset with lighter ammo the speed goes worse too. <br>The balance is the trick.</div><div class="clear"></div><div class="signature_div">

    using a lighter ammo i got a 10mps more (with same bandset).....<br>i think is all a question of drawlenght... each TB color band got a max speed per elongation....
