i don't see what the big deal with weight is. a pro only weighs 7 pounds which is like a pound heavier then the new A and the pros stronger. id go with the pro, and depending on how big you are i would recommend reinforcements
i was at tic and this little kid was doing backflips into the foam and on like the second one his back hit the side of the box...but then he got up and did a frontflip into it
