They're very light inner springs, so not so worried about that. I read about needing smooth edge .500 seals if using inner springs, but not sure these are that. I'm just going to watch them to see what happens. You need to have a certain amount of spring pressure and I'm hoping these professionals knew what they were doing deep inside, but based upon the stuff I can see outside... I'm not so certain about that.

I'm not freaking or anything. Just shaking my head often and thinking who else is getting this level of service from these guys. I'm thinking of doing this sort of work for my new job. Seems like there's a need.
