After following this thread I made the decision to go with the R3 Rage...right price and the opportunity to get protection while riding right seat with student in street car 3-point belts.

It turns out that Simpson has discontinued the R3 Rage. So the only option to keep the 3-point option is to step up to the $1000 R3. So back to the decision process.

There are some dealers that have the R3 Rage (most only have small and large sizes) left in stock, but you may lose one year of certification since they would have been manufactured sometime in 2011. I did call Safety Solutions and they say that they will continue to recertify the R3 Rage even though they no longer produce them.

I do have another question to provide to anyone actually using either R3 design (or a hybrid...) When properly tightened around the chest, do these restraints cause any problems for circulation in a cool shirt?
