Polyester will heat up 10 times what polypropylene will.  So you would have
to have about 10 times the number of caps that a polypropylene MMC would.
Of course, you can try for less ;-)  Polyester does take more heat,
however.  You can build a good MMC out of polyester caps but you will need
a lot more of them which normally would counter the lower cost.  However,
if you already have them...
