Just practice my famousindoor safety rule #3-249B.
"Always remember to unscrew the field point from your arrow when you are drawing a bow indoors. This way it makes less of a mess if bow is accidentally fired."
So even if your release fires unexpectedly, a blunt arrow may not pass through the garage wall like you previously expected it to.
I'm not an expert on releases, but I did stay at a Holiday Inn once.
So take my advice, try and test out some various types of releases. This is best way to decide if you want to use one or not. Personal preference is key.
Ohh,BTW, did you ever get those 78 year old strings replaced?
