Rub a little beeswax lip balm on the end of the string before putting it on and you’ll get more response.
My 2014 eh and 2015 Baldwin both have stock walnut woodthread axles and play with exactly the response I want, but every time I replace the string it is initially unresponsive and I have to throw half a dozen or more long sleepers/pinwheels to break in the string.
When I had a maple woodthread axle in the eh it would never get enough response unless I added the lip balm.
