yea, I used a solution that doesn't rely on the rope with the timer and used separate ropes for the catcher. I tried to do it with just the rope/w timer alone, and it's hard to get the dillo down fast enough before that timer goes and at the same time making sure the catcher doesn't break.
There are just so many variables such as the rockets spinning, where and when the rockets go through the cloth, etc, so the whole thing is sensitive to any small changes.
I know I shouldn't be talking about the solution that much, but there are only so many things you can do to the catcher.
