Im having a hard time figuring out how long i should get my arrows.I want the Easton ST Epics. 400 spine

i got a 27 inch draw length

Im just trying to figure all the weights and lengths of arrows. its very confusing[&:]

howd ya figure out a 400 spine if you dont know arrow legnth?? arrow legnth depends on the bow and rest set up and personal prefrence. i have epic 400s..but for a 67lb 28inch draw i was underspined at 29 inches..had to goto 27inches to get correct spine and BH flight. i got about 1/4 inch MAX between my head and rest prongs and the rest is backed out as close to the string as possible..i dont personally like it that short. that thing falls off and im bleeding for sure!! and if i draw too far it flys off...luckily that happend with my practice head that been shot a million times and i didnt draw blood...but should seen me tryin to get the arrow back on the rest so i could let my draw down...my backwall on my draw is pretty solid with a nice valley..but that time i know i drew to hard and too long..and thats what happened..

my advice...goto a shop and have them use their measuring arrow and see what you need. they usually have a full 32 inch arrow marker with measurements...you knock it and draw and they will tell you what you need
