I dunno, sounds a bit drastic to me. The cupping kit is already a couple of inches longer than the power kits and the length of that is fixed (at least in my simple world until you correct me) by the cupping kit screw bit.
Wouldn't cutting the kits back devalue them/the pole when I come to sell it on some whim in the future? Very tempted by some of the prices on the signature range at the moment.
Wont devalue them at all,my signature 1000 came pre-bushed,but i still cut them back to accommodate the thickest elastic,im likely to use,and put a drennan extra long super-slick bush in them,basically i dont want any bend in the tip itself,bites are easier to hit,especially from F1,s etc,no tip bounce when shipping out with kinder pots etc, laccy never sticks,loads of positives mate.,obviously you need to try and keep them all the same,and the cupping kit,roughly the same.Gazza
I knot both ends. Double the elastic and elastic the top kit as if it was a single elastic, don't overthink it, it ain't rocket science if it was I couldn't do it coz I are mostly fick.
