This is in regards to the other post about backing up your hand ascender. I use my Microcender inplace of the Croll when I SRT. I finally figured out how to make my MC follow up the rope better. I took shock cord for fixing tent poles and tied it through holes that already existed in the MC. I then tied it to a biner which I will clip to my hand ascender. So far it works well. In the pics I left the shock cord long in case I need to adjust. Let me know what you think. Pics are not the best, but I think they show what I did.
