I can’t understand your approach. If so many plug-ins crash on your system, there is something wrong with your system, or you are using only strange plug-in versions.
I once had many crashes when GP was loading plug-ins which load large sample sets. It turned out that a memory bar in the RAM was currupt.
Building a second GP gig as a back-up for each and every song using completely different plug-ins for the same sounds is neither effective nor professional. You need to fix what is wrong with your system.
As this is a thread on TDR limiter: It never crashed on my system (Win10) so I would see not a single reason for replacing it.
