pitchin and flippin are two totally different presentations. If you want a rod for each specific technique then your flippin rod will be slightly longer, extra fast tip and heavy backbone. A pitchin rod will be slightly shorter, fast tip and a lot of back bone. Very similiar to a flippin rod but just not as heavy duty.
I will make fifty pitches to one flip just because the type cover I fish the most is not set up to do a true flip. There is zero vegetation in the three lakes I primarily fish. Most flippin is done around vegetation but there is some that can be done around wood. My two pitchin rods are GLoomis 844 7' heavy power, fast tip, Gloomis 855 7'1" extra heavy and extra fast tip. My flippin rod that I rarely use is a GLoomis 895 7'5" extra heavy and fast tip.
