Kinetic / Energy / Leaping, best Epic Pool?

[Doktor_Q]

I'm running a Kinetic Melee / Energy Aura brute (plus the Leaping attacks) who just hit level 35, and I'm trying to decide which Epic pool to take. For simple thematic Energy Mastery seems like it'd fit, but I'm already doing energy damage with nearly all of my attacks, and I'm not sure I need to invest in more endurance management and accuracy powers, rather than crowd control. Is there any common wisdom for choosing your epic pool? I mostly play solo, so I'm more focused on self-sufficiency than team synergy.
