When I did my CPL I did 15hrs on the Warrior and 10hrs on the Arrow. The first 15hrs are basically brushing up on handling, nav, PFL's, emergencies, instrument flying etc anyway so it doesnt really make a difference what aircraft your flying...
Once you start to get that nailed you will be introduced to doing them in a complex type which I found worked very well for me. I got through the course in min time/min hours and was happy with the way things went.
Best of luck!
