Oppies give you more bang for your buck and you don't have to convert them to make money. With 2 years running on current one, you are getting more leverage with your money. Spending a $1000 for example and buying oppies at 0.002 will get you 500000 oppies. Spending $1000 on heads at 0.005 gets you 200000 shares. If they both go up one pip, you can see you will have a greater return on the oppies.
Using your scenario of adding in the strike price, the oppies would be in minus territory at the current price, compared to the heads at 0.005 and that is not the case with the market.
