The HTP hybrid will have the same issue and the same solutions. Classic, head
end injected hybrids all have the same issues and it worsens exponentially as
they upscale.

Yeah, not worth my time. I was working on a manifold idea for the Bloodhound
motor at one time for a full pressure test. HTP hybrid wont have the same
issue. Adding a bit of AP to the HTPB (5%) was also an interesting solution for
that motor.
Yeah, I just can't get into the hybrids. Not my thing unless they are
pressurized versions.
