A little more on regulators...
Yes, regulators with elastomeric material for the diaphragm can degrade due to propane depending on which elastomer is used. I know Victor makes stainless steel diaphragms in their medium-duty regs because I own one and have used it with propane gas for over 20 years with no issues.

So, get one with a metal diaphragm and you can run either gas, no worries...or check the specs on the regulator you have and if its metal, you're golden. Also, if running propane on an acetylene reg, you can ignore the 15psi max.

Last thing, those flashbacks can and usually do reduce pressure to the torch so you need to raise it to compensate. Normally only 1-2 psi.

Good luck!
