Is that right? Your shooting a .39" spine for a 55lb trad bow???? Well your special, thats the stiffest spine I seen used for a trad bow of 55lbs. Most normal folk use a 2018, possible 2020. I used a simular spine 2216 for my 66lb black widow with 190gr point.

Don't worry, you removed all doubt for us all with that statement.
