CTM Sleeping, page-13

Yes - I have both OAs and OBs (no heads) but they are very different stories! OAs are a high risk, high leverage short term play (of course they may be converted but I don't tend to do that due to the capital constraints of paying for the conversion, and it messes up my book-keeping!) while OBs are a longer term play and they were very cheap (now not so much...)
I think both will do well and OBs might be spectacular later on (I don't plan to sell those for a while).
I am not surprised at their recent behaviour - OAs are often at a negative premium now (while CTM's "uncertainty" exists near the 1c strike value) - if they were to make a significant company making announcement/discovery then we would not be seeing that negative premium any more - at worst they would go comfortably at par value. The OBs are usually at a healthy time premium and hold their price well even when the heads slip a little. They are a pretty safe bet and if I were entering now, I would be mixing heads with OBs. I had OAs from some time back which is why I am a mix of OAs and OBs now. Long term I would love to be heavily into the heads if things go well.
This is all still very exciting and the time between now and late April totally fascinating and I hope it will be a happy time for us all
