Thanks for all the replies, really helpful.

I just try and mix it up when I can, so long pass from the floor and then once every set or so I'll take a few steps and then pass it on.

Is that basically the gist of it, do a bit of both to keep them guessing? Obviously if one marker is left on the floor I'll run

If you're playing in a team where the gameplan is for the props to take the first two carries and then pass it to the halfback on the third then it's very basic indeed.
