Im now training to be a scrum half, is there any way or technique i can use to get my passes faster and longer? would anyone recommend the 'Morgans Pass Developer' ball?

Practice

There's only one way: Practice, practice, practice......

If you havn't got your spin pass technique sorted then focus on that, other than that it's just practice to build up the accuracy and power. Go out with a mate and just practice passing, like you said faster and longer, as you go on. Your best off using the type of ball that you'll be playing with in games to get used to it, but really that won't matter too much.
