I think this was previously discussed for other reasons but for a long long time we have always just left the hanger sizing cases and +H in the load cases so you don't have to use a different set of load cases if you add a spring or delete a spring. The hanger sizing and +H has no impact on a calc without a spring.

The only glitch is that for the older CII versions (I am still using CII 2014 since I been on this current project for over 5 years) is the output animation sequence was offset be 2 load cases, i.e., if you animate case 5 it is actually case 3. This may be OK on more current versions. I have only used the newer versions helping peers troubleshoot issues.
