I did my flying training with the great John Eglan of Queensland Aviation Services 2002-2003, his recommendation to me was to do the last 20hrs of CPL training in a twin (in my case, I did it in a PA34).
Next up was the CMEIR, he recommended 20hrs in a C172 to get the basics down patt, then finish the training and rating in the twin.
Everyone told me they were just trying to generate more money for themselves, but Johns reasoning was spot on and couldn't have been better for me. He said, every single twin hour will help me gain that first job and especially entry into the multi world.
Sure enough after just 200hrs of glider towing, I got my first start in the charter world flying a mixture of PA32's and C310's! From there it was a fun ride to the turbo-prop and jet RPT world!
So if money is no issue for you, go for the twin option (but make it a useful one!)..
