After the web collapses there are only two options; you either cease or you rebuild. Hopefully, rebuilding with a new found wisdom. Making sure each strand is securely fastened and anchored. Is the web weak if it is rebuilt with some of the same structures? Sometimes it is unavoidable, and without change I have to say yes it is very weak in those spots. The strands are thin in places, looming to snap at anytime whether they will or not is not the issue. The ones laid out anew are laid with a firmer foundation due to more research, a caution in mind and contemplation before they are spun. Meanwhile the original web lays scattered at your feet as a reminder of how with over confidence your down fall can come swiftly.
