just to be clear; i casually threw instead to see how much my string would stretch on average. i also recorded how long i threw in those 3 days.
before
after
i used the r2fg 60/40 poly/cotton blend that @codinghorror sent me for the contest. i dont use different types of strings at once, i usually just use what i have. so ill probably be using these strings for awhile. the difference in the two strings is about 6 cm . i also got an average of 60 minutes of throwing a day, which i would say is pretty average to me. this means that every five minutes of throwing with this string for me, the string stretches half a centimeter.
Hey guys just a lil update. I finished testing an Airetic and a homemade fuzzy nylon (thank you @smittylube). The final stretch test will be using one of @smileypants707 nylon/poly whites (thanks Mr. Pants for the donation to our noble cause.) Working a split shift today so fingers crossed, results maybe posted by end of day.
Ok guys, the long awaited results of my stretch science involving fuzzy ‘premium’ nylons. The test samples were an Airetic neurotic and a custom job from the hands of @smittylube. Both strings were played for approx 4-5 hours each, I tried to play as hard as possible to achieve maximum stretch that would occur naturally, which is to say I did not just pull them really really hard. So here we go:
This is the Airetic at the beginning, not prestretched. and after several hours of play
Now @smittylube’s fuzzy nylon from start to finish:
So, as we can see, both strings stretched a good 3 inches. I switched between a Marco, a MYY N12, and a Topyo Meta while testing. And it should be noted that Airetic does warn that their strings ‘play a little long’, so I think it safe to say this is what they mean. Thanks everyone for your patience, if anyone wants to know more just ask me. Oh and avg temp during testing was 68F with humidity averaging 42%.
They play really well too. The fuzzy nylons are my favorite, very soft and slick. @smittylube sent me some samples of his homespun threads that I think are on par with Airetic. However, Smiley’s got a nice nylon/poly blend string, and Zipline’s are my favorite as far as straight poly goes.
