Doewhacker asked about tuning, this is an example of tuning an arrow to bow just by cutting. My tune (shown above) is full length 340s and 300g heads. This top group is 400s with 300g heads but cut 2” shorter bottom are still 340s. The 400s end up a bit lighte too due to weaker spine and cutting. But same bow, arrow type, and head weight. Only difference is 400 vs 340 and 2” cut off. They will both work.
