Just an update to an earlier post in this discussion.
At 3202 haste (I'm almost exactly there right now), you can comfortably fit in 4 mind spikes plus 2 ticks of a mind flay inbetween each Mind Blast. The Mind Blast may not line up perfectly, the last one always gets 3 orbs, so even though there's a minor delay, the timing still lines up.
Withe heroism/bloodlust, or the insignia trinket procced, you can get 5 + a mind flay.
