can someone with the program that figures proper arrow spine help me out please? or can someone tell me a way of figuring this myself? ive ran searches but they ALWAYS come up empty.

i shoot 29" DL
Vectrix 60-70 set at 62-64 lbs
arrows are 28"
100 grain broadheads
blazers and wraps
idk the weight of my arrow if thats needed, but kind of irrelevant because im looking into new arrows, and just checking what the spine should be for these arrows.

so for these specs, what spine would best fit my setup?doesthe weight of the arrow matter?

i just reinstalled my WB so ill be attempting paper and walk back tuning again this week.
