I have had my best accuracy and speed from Hybrid 100v. I have heard that there is some concern over temperature stability of Hybrid 100V, I can only give my experience.

Loaded up max load with 100grain TTSX, sighted rifle in at about 17 degress Celcius 63 F, shot at target a few months later at -2 Celcius 28F, there was no discernible change in where the rifle shot between the two temperatures.
