I have just been calculating what will be a better purchase on expiry date. With heads at 21 cents and oppies at 9.5 cents, you are better off buying the oppies if you are holding till then and if you think CKK share price will be above 47 cents in Nov 2012. At this point you will get a bit above a 100% return on both investments at current prices.

I'm planning to convert at this stage and believe oppies are the way to go still
