As the string gets old it can bunch up in the gap, and the little twists get stuck in the holes.
Often I can’t even pick it out, and end up having to cut the string into pieces to get it out.
The times I have been able to tug it or pick it out, there hasn’t been an axle knot, and I’ve seen the little twists down in the holes.
Anyone else have this problem with their fixed axle yoyos that have response holes?
The tight bunched up bind can happen on other response systems, but the hole can really get a death grip on the string.
Even so, it’s my favorite type of fixed axle response.
