Need help to build a Dual Totem Spork

I too am doing a dual spork totem build, loosely based around this threads suggestions. Overall my dps is pretty reliable, Spark is at about 115 now and one cast of Conductivity brings most mobs in Cruel to their knees. Sitting on 7 unused points only cause I can't decide where I want to end up.

Any advice? http://www.pathofexile.com/passive-skill-tree/AAAAAgUABVsRLRZAHwIpTyycLKctHzLRPAVDY0SrRUdG11WuWPVZ81orXcZgbWaebRlxTXYRfIN-r4Kbg_eFfYuMjRmPpprPncSf36PytQS3MbiTwBrBtMy3zfrVddlf3Yzd8-AS4XPkIuTs5kzsOO0g73zyzg==
