    Today, after my high tapered and short bands break again (it lives for 30/40 shoots) i decided to build a less tapered and long bands (always using joerg calc).<br>Before i set all parameters to 9 (max power)<br>No i set all to paramters 6 (quite good power)<br><br>I have 90 cm half butterly drawlenght<br><br>So the ultra power bands was<br>35mm at fork<br>14mm at pouch<br>2 x side<br>19,5 cm lenght<br><br>The New one (should be weaker) is<br>33mm at fork<br>17mm at pouch<br>2 x side<br>22,5 cm lenght<br><br>With old one i shoot 7g steel ball at about 60mps<br>With new (SHOULD BE WEAKER) i shoot about 72mps<br><br>How is possible?<br>(today is a little more hot, about 15° C, why other day was 5-10°C)<br><br>Can only temperature make more than 10mps???<br><br>I did newer bands coz i was frustrated to remake band every 5 days.<br><br>Thank you <br>Ottavio

    This one is longer right? Maybe you are pulling it further?<br>More acceleration length is more power.

    Are you using TB Gold? Something is very wrong if you get only 30 to 40 shots out of each bandset. I use much thinner and weaker TB Silver, with a smilar taper (2-1cm) for 8mm steel balls (much lighter than 7g) and I easily get 200 or 300 shots, maybe more.<br><br>And my drawlength is 108cm (I anchor with my first thumb joint at my earlobe) for an active bandlength of less than 20cm.

    that's because I used in the first band-set a several mre hight taper more than 2/1, I think over that rapport the bands break really beofre...<br>i used joerg calc and set power all to 9
