this ain't a real poll unless you set it up as such ("post a poll").
ya know, it really doesn't much matter what string ya use as long as it works for ya. why would it ever matter what other folks are using? what you really need to understand are bowstring basics, and then make yer choice based on facts.
if yer bow isn't of modern build, you probably should only be using dacron (polyester), or bad things might happen to yer bow and you and maybe others nearby when the limbs fragment on release.
if yer bow is of reasonably recent modern build, it's probably "approved" for modern string fiber ("hmpe" = dyneema, vectran, spectra, etc - all are polyethylene in origin). yes, you could stick a dacron string on a modern bow, but why? the performance benefits of hmpe (high modulus polyethylene) strings far outweighs anything that dacron can offer. we're NOT talking limb or arrow speed, we're talking CONSISTENCY.
let's do the scientific math approach. b50 dacron is s'posed to break at 50# but in reality does so at around 45# .... 5# less also for b55 dacron.
at most, a good and overly safe tensile strength bowstring formula is 12 x the bow's holding weight. some folks go down to 10 or even 8 x the holding weight.
so a 43# bow (12sx43# = 516#) needs a minimum of 12 strands of dacron polyester (12Sx45# = 540#). that holding weight would also be fine at 10 strands (10Sx45# = 450#). or 6 strands of hmpe polyethylene (6Sx100# = 600#). add to the mix the durability factor, so low count hmpe strings might be better served by adding two more strands to the count (8Sx100# = 800#).
for my 55# mohawk i use 8 strand d'02 endless strings exclusively ... 12sx55# = 660# (the tensile strength that needs to be met) ... 8Sx100# = 800# (the tensile strength of 8 strands of d'02. in reality, almost all hmpe fibers will break at higher than 100# tensile strength - most at the 120# mark.
hope this helps.
