Don't get me wrong, i love twins, i just had to get the training and the flight expierence in them to know it's a bad business model.
My, you have done well. Only a couple of months ago you were doing your PPL and telling us the Mooney was the best thing in the world. Now you are an expert on twin flying. I am impressed indeed.
As pace points out the twin does have some advantages over a single in certain circumstances and does require currency. I only have around 700hrs of multi time so can't compare to his experience but my limited experience agrees with his.
Notwithstanding this I will take the Mirage over any of the twins based on speed and economy!!
