An Update on my post, I tried hybrid yesterday, went to KP and on Bonecrusher did 1350 dps on average (we did both normal and hard mode on this boss and DPS didnt really change much). Looks like hybrid is significantly better than lightning, which makes sense since movement doesn't affect it as much.
On the test dummys, with no class buffs other than the SI one, and no debuffs on the boss as I was the only one hitting it, I was at 1250 using hybrid, and 1150 using lightning. Hybrid wins out again with a 100 dps difference.
