i have been coached to tuck my leg after i have swung more then 90 degrees (my back parallel to the ground) then to break my trail leg down and tuck into a tight ball as far back as possible and to kick my legs straight up the pole and snap my hips tight up against it. (ex: brad walker 6m,

I've been told by other coaches at meets that i should keep that leg straight throughout my jump to help me get on bigger poles, but i don't need to get on bigger poles, i need to get back further and quicker so heres how i took it
Breaking down the trail leg (not instantly!, but after most of the swing)
Pros:
getting back quicker and further
more explosive/aggressive off the top of the pole
cons:
need a better drive to get on larger poles because the leg does not put more energy into the pole
straight trail leg
pros:
don't need as good a drive to bend the pole as much with the power of the leg swinging (although a good drive is still very important)
cons:
need a lot more strength to swing quickly and completely upside down
if you don't have the strength (or you are just learning) then you need to give up a lot of your take off to swing faster(

not as "explosive" off the top of the pole
i would just like to get your opinion as to why the petrov model is better then breaking down the trail leg because my training is based around breaking down the trail leg and anyone who could add to the pros or cons of eathier list or elaborate or correct anything i have said because this has been bugging me since i started worrying about technique thanks
