I use a trackball and find it makes me more productive and causes less strain
Most other people use a normal mouse
Since I also have a lot of muscle memory using normal mice, I am able to quickly adjust to working on a new PC
Others struggle when they have to take over my PC and show me something by navigating with my trackball
I am guessing this might be similar -- since OP does have years or muscle memory with normal keyboards anyway to back them up
