Hi Brian
Finally managed to get back onto this and here are my thoughts:
1) As you suggested - I'm only going to use a second "stripped note details" attribute for the reminder as the note seems to work as the format with the line breaking makes the data much easier to read. Stil a bit long but no worries
2) On every note that is added i'm going to create a seprate calculated field on the note object that will use the "stripping" syntax and store it as a second field to use if needed
3) my process will only use the stripped text on the reminder and only when the note was created by the LDSDInboundMail account as this is the user that creates the note with the incident is updated by email.
I think that was pretty much your idea number 2. Thanks Brian 
Probably doesn't add much but here is the screenshot of the process (the add status record just allows me to return the note the status that it was previously at)

Just got to get a handle on the stripping logioc as I'm no programmer
