If you can't find "an answer to what works in the Creed" it's because you haven't tried anything for yourself. Never ask an online question that you are able to answer for yourself, by doing work for yourself.

To the folks asking about Superformance and RL-17:
Both are much more stable with temps, than H4350, HOWEVER:
RL-17 is progressive, and Superformance is VERY VERY progressive in burning curve!!! Don't think you can"walk up the velocity" and gain speed withing pressure limits!!
Here are what the curves look like from work were did a few years ago.

P.S. if all you can see in this is the speed and pressure, you need you punch yourself in the damn face.
