I agree its a sizable risk to heat up a blade.
But I have heated most of my composite blades, it has been a disaster for my TPS stick (I had already broken the shaft so I wanted to experiment with the blade) - my Mission Hex core and Bauer blades came thru with flying colors. Mission / Bauer / TPS is all I have ever used so... Bthe auer actually worked well for over 2 years, Mission last about 9-10 months.
Based on the results of my prior TPS blade experiment (and the blade type I have now) I think I will hold off until the blade has served its time (gets chipped, etc.) or I can get a handle on working with a greater loft than I am comfortable with.
It depends on the design of the blade construction.
I'm a big believer in trial and error with my sticks - but only when my costly new stick has seen its day and I have a good replacement I'm comfortable with.
