I can tell you that tecnica uses three different types of plastic for the diablos. I did not like this design from the moment i saw it, so i'm not surprised it does not respond well to grinding or softening or... anything.
There are a couple of bootfitters who post here and they will probably help you.
FWIW, i weigh 155lbs. and i tried the Fire (90 flex?) and they were rediculosly soft. Again, IMO the problem is that they are too soft for you (even w/o any softening done).
