I know where you are coming from TB and understand your comment but it is a matter of personal choice for different reasons.

The A's are the option to buy for a reason (the exercise price obviously) but I feel and believe that in general option trading rather then the option conversion scenario the difference will be minimal between the the A's and the B's and at different times in option trading over the past few months this has been the case and a few times the B's were more sought after then the A's in fact.

Trust me I have plenty of A's and ESI heads but I have trouble at present ignoring the fact that I can just basically achieve more 'bang for my buck' by doing more B's which no doubt I will trade at hopefully multiples of their current Share Price.

Hope I answered your Q and hope again that we are all having to do option conversion calculations down the track - If I and plenty of mates didn't believe that, I and them wouldn't be buying.
