Whistle fuel phlegmatizer question

[rocketboy242]

Hey guys,

I've had great success with 70/30 perc/ benzo

No catalyst or phlegmatizer.

Just the two comps mixed well and granulated with camp fuel.

Once dry, it presses really nice at 6500 psi.

1# motors with a 2" core take off like a bullet.

Wondering if there are any dangers not using a phlegmatizer from a sensitivity point of view?
