    Yes, your draw length would be 800 mm. This means that the active band length (the part that stretches when you draw out) should be min. 14 cm and max 27 cm. The shorter, the higher the draw weight, the faster the shot. But also the band life goes down. <br><br>Long bands are weaker but last longer.

    Well, you have to be strong to draw TTB to 5,5!

    I cut first 2 x 270mm long.<br>I tested:<br><br>for 800mm stretch -> 10kg <br>900mm -> 11kg<br>1000mm -> 12kg<br><br>See it linear.<br><br>I test 270mm long and later cut to 240-250mm. I think this is the best for me.<br>(Gold thera band on way... <img src="http://illiweb.com/fa/i/smiles/icon_twisted.gif" alt="Twisted Evil" longdesc="13"> )
