Why do you want an arrow 1.5" longer than your draw?
Cut it to 29" and add heavier point. The arrow will act stiffer and be heavier in grain weight.
What is your actual bow weight at your draw length? Have you ever scaled it.
1916's were too weak for your setup. 2016's may be right but 2018's would be better, or 2114's if you absolutely want to use a 30" BOP arrow. Remember every inch beyond 28" weakens the spine by about 5#. Every 25 grains additional point weight weakens spine by about 5#.
1916 spines at 53#
2016 spines at 62#
2114 spines at 64#
2018 spines at 68#
All above are for 28"BOP arrow.
