I totally agree with you Rick. Sach, if you're making a two hour flight, why would you only fly 1.5 hours. I would recommend that if you have the hours and more importantly have been "blessed" by insurance. Then you and the other pilot ought to be changing seats after every leg. Sort of "spread the wealth" if you will. If you are low time, then the other pilot ought to be letting you fly to get your time up so that you can be covered under the insurance.
