I have been shooting the Gen3 .45mm for a couple of months now and it's still my favourite band. The measurements and details are in my posting below.  This band is the best I have found for shooting 7mm steel at 10 to 20 metres.  The draw weight is mild and very comfortable but velocity is still up there.  The band doesn't stack up with the cut I am shooting.  It's smooth all the way to 32" and I can even draw slightly longer if that was my style.  My 20 yard (18m) accuracy has improved and I attribute this to the mild draw weight that I can use with this band.
