First flight arrow.

.  Right now the flexion of the shaft measures .525” on my little home made spine tester which put it’s around 50lbs. 

that deflection is with a 2 lb weight?

where does the 50 come from?

Wow thanks Del.  I overlooked this important detail.  Thanks for sending this.  I’ll be making some adjustments.   
Might be worth reading this, as there are two very different ways of "measuring" spine.

Ok so after redoing my math thanks to Del btw… I now have 4 shafts ranging from 30# to 50#.  This should give me a good idea what this bow likes.  The weights are varied a bit range from 205grains to 233grains.  I’ll get them sealed up here next few days and then get them fletched.

  On short flight arrows I have never heard of actually calling the number for spine. Most people just talk about defection because the actual spine is so low. Cutting an arrow from 30" to 25" will add about 25# spine to an arrow. That's why we measure at 22".
