I have both the Break Solid and the BP and don't see a difference in reaction shape between the 2 of them. They both have the same layout but the BP needs more oil to get that reaction. On a slightly less volume the BP reads much earlier due to the stronger cover. A smaller angle to the VAL will increase the angularity. I have a couple of low rev guys I drill for that we use 20-30 degree angles to help the backend.
