Hello all, I got a question for ya'll....

Would it be a bad idea to train with two instuctors and two different airplanes at the same time?

Why I ask - I'm saving money to pay cash for my flight training, it will take me about one more year from now before I can quit my job and train full time. In the meantime I've been working on my Private on Saturdays. My instructor does the church and family thing on Sundays and on weekdays I'm too exhausted after work to be IMSAFE. So long story short my instructor has an important job that has him traveling all over and sometimes we can't fly on Saturdays because he is out of town. Needless to say I was pretty bummed yesterday as there wasn't a cloud in the sky and it would have been the first time I was up in calm winds and not at minimums ( yes I got broken in good ) Ok wrapping this up... I get along with the instructor fine and stuff like that but I was thinking of finding someone who can fly Sundays as well and well... that would be in a Piper Cherokee and I've been flying in a 172M.

So what do ya'll think? Are the two planes similar enough that it wouldn't matter or would the experience in two different planes benefit me in the long run? or for that matter would having the wisdom of two different instuctors experience be as beneficial as it sounds? I'll be sticking to Jeppesen's 141 syllabus so as long as the instructors are straight up I should just be able to keep working my way through the syllabus right?

thanks ya'll, Jeff
