The commercial checkride can be split up and taken in two airplanes, one complex, one non. I plan on doing so because I can use the non-complex for no cost while I have to pay for the complex. I plan on demonstrating that I can takeoff and land the complex (which should be evident by the fact I have the endorsement) and do everything else in the non complex. The FAA is reconsidering the need to even have a complex airplane for the commercial checkride (it wasn't always a requirement). If you have ten or more hours in a complex and the endorsement, why do need one for the check? I actually find it more difficult to fly the maneuvers in the non-complex. Maybe the FAA should require both a complex and high performance endorsement for commercial applicants but allow anything for the checkride.
