In reply to GoneFishing111:
It sounds as if you have a certain amount of twisting "embedded" in the rope. This can happen over time, or it can happen immediately if you don't uncoil a brand-new rope correctly.
If this is true, then no coiling method is going to do anything. (Proper coiling can keep the twisting from becoming worse, but can't relieve what is already there.) If you can hang the rope free for a while from the top of a crag with a little weight on it, this will give it a chance to unwind. Otherwise, hang a draw somewhere, clip in an end of the rope, and pull the entire rope through. Do this back and forth a few times.
Once you've removed at least some of the embedded twists, butterfly rather than mountaineer coiling is more likely to keep the rope twist-free. It is also helpful to not have the second tie in on the first pitch until the leader has lead the pitch and pulled up all the slack. This gives the rope a chance to unwind each time you climb and avoids trapping in twists by "freezing" both ends. Just make sure to pay attention so that the leader doesn't pull the ends of the rope out of reach!
(In the US, this suggestion generally elicits a chorus of denunciations, since the currently demanded partner-checking can't be carried out on an unroped second.)
I usually make a backpack coil with the rope coiled double. This means that twists are put in the ends in opposite senses (from the perspective of a straight rope path) and so they cancel each other out (if they get the chance when the rope is used).
