First, if you currently have Monroe struts on the car they have a lifetime warranty. If you go to a Monroe dealer, like Pep Boys, they should give you credit for a new strut, however, labor is not covered nor would the other strut unless it is also bad. I also use the Sensa-Trac front and rear and have been happy with the ride.

I don't think the cost difference would justify the difference in the ride & handling. I could be wrong, since I have not used the Reflex.

Springs are a matter of personal choice, I have 175K on mine without replacement and they do not sag or show any signs of giving up. I would not think you need springs, unless the car is sagging. (Lower than when new).

I replaced all of my struts at the same time. The rears were ALC (auto level control) however, I had a bad compressor, so I installed a manual fill kit (Monroe AK-29) and set it once and have not had to add or remove any air since. I run about 22 psi in the rear.
