Hi I'm Jacob with the Northern Illinois University team, I was wondering what exactly the difference if any is there between the percy model that is shown in the rule book where there are 3 circles and distances between the centers and the full body they used at competition. I know the model at comp had bent knees and rounded feet. I would guess the general shape both would fit in are the same but i feel that the full body might restrict or allow different designs. Has anyone come across anything that using one model could change a design over the other? and is there a way to get a model like the one that is used at comp.
