Not the best cycle in the world, but I've seen worse. I'd keep your test/eq like you've had it and finish the cycle, run your pct, stay off for a while, then get back on...but this time plan to do it a little tighter.
BTW, if arimidex didn't work for you last time, either it was some crap, or you were not using enough, or skipping doses. Arimidex is willalways get the job done is used correctly.
