do you have any numbers for this?
not a witch hunt. just trying to put some numbers to this
I do not. I do know that on my stretching jig I can put a load of around 300# on a polyester string and get a good 2.5-3" stretch (that contracts when the load is removed). With a 100% HMPE string, maybe half an inch and very little contracts. With a HMPE/LCP blend, even less and almost all of that is creep (doesn't contract).
...so the consistency id say is marketing hype.
Call it what you will. There's a reason compound bow companies spend a lot of time and money researching string materials, and professional shooters as well. Coach Mel Nichols (Olympic Coach--not the type you normally hear people claiming to be on message boards--he actually coaches Olympians. He coaches Brady Ellison, among others) showed me some of what they go through to pick a string. It was amazing to a string nerd like myself. I don't mean this to be harsh, but calling it "marketing hype" just tells me you aren't very educated on bowstring materials...otherwise you would know better.
so what is the difference if most cant spot the difference
As I said...consistency, durability, stability, and noise. Most folks don't study this stuff. They rely on the people who do, and trust their judgement. Most won't shoot well enough to discern the difference in consistency and stability. That doesn't mean it isn't there. Just like most can't shoot the difference in a $200 bow and a $2,000 bow, but if they can afford it most will choose the $2,000 bow.
until you start hitting high energy setups. such as long draws. and high poundages.
The lightest bow I've shot in several years is 52@31. The bow I shot the longest (and still have it) is 66@30.5". I shot it for tournaments, hunting, and fun for 15 years or so. Never had polyester string on it. Never had a problem with it. My arrows averaged around 9 grains per pound. Not heavy, not light.
even seasoned professionals in the upper teirs of the industry are advising you avoid the likes of 452X
Depends on who you ask. You can find someone to agree or disagree with anything you ask. Almost always, when a bow fails, the first thing to get the blame is the string. I have yet to see any kind of report or test that proves a specific failure was due just to a string. It's usually factors like dry-fires, light arrows, number of shots, etc. that are not factored in. 452X is the benchmark in the compound world, but BCY-X has also made it's mark.
but one thing is for sure. string makers, AND strand makers don't have to pick up the warrenties for limb failures. and whats great. cant even tell you if there is a performance gain in speed OR points.
No, they don't. String makers like myself only have our reputations that took decades to build on the line. There's a reason I was sponsored by the world's largest traditional-only store to make a video, and why I work with BCY at shows. It's sure not for my looks.
I already stated what it takes for a performance gain from a string. Good shooting form, like a proper release, will give you more of a gain than a string will. Points...well, talk to people who make a living shooting bows accurately and ask what they are using. Speaks for itself.
if I were to put a bet on the next limb failure being on a less elastic string type. no one here at border would accept the bet.
And nobody is arguing that is your call. And I can say I have been shooting a Samick Journey, one of the absolute cheapest bows on the market, for 4 years with nothing but BCY-X strings (endless and Flemish), with no problems at all. I can't remember exactly, but I think my arrows are around 8 gpp. I know they aren't heavy. 31" draw. I bought this bow just to test this material. So far, so good.
If there are other companies that are having similar problems, I haven't heard from any of them.
