with Powersurge just slotted for recharge and your other shields damage res on all but toxic (52%) is maxed but toxic is quite common high level (TT's,commandos,scouts etc).
Powersink is a really good power and i do find i use it alot so i would prefer to atleast slot it with 3 recharge.
alltho i do have both powers 6 slotted i think its down to personal choice and what enviroment your playing in ie PVE or PVP.

No familiar with power surge, but would definitely 6 slot power sink.
Recharge is the important slotting for Power Sink...add end mods to suit your needs.

My SS/elec is lvl37 atm, and I'm running a 6-slotted power sink.
Power sink is sooo great, drains a lvl+3 boss for over 80% Muhaha
Haven't tried it in PvP, but guess it's a pain in the <bleep> of the opponent

Hi,
i'm now shortly before level 35 with my fire/ela brute and have a question concerning the power slotting on level 35 (power sink) and 38 (power surge).
In my build i have reserved 6 slots for each so far, so thats no problem. Recently i talked to some other Ela brutes ingame, who told me that 6 slotting these might be to much. For power sink 4 slot (2 endmod, 2 recharg) should be sufficient in most situations. For power sure 3 recharges should be enough cause with the shields up i would already reach the damres cap with exception of toxic. Is this true ? What would you suggest ?
Thanks in advance!
