hi...any 3/4m will be fine for playing around and developing kite skills
you need these skills before ever considering going up
you want a kite for most occasions till you need more specific equipment
3/4..is great for learning to landboard and buggy as well
it is not for jumping unless your like under 110#...
i hope your just looking to build a quiver and that's where your starting
seems the ones you are asking about are pretty aggressive models
welcome
