As above Tim welcome back, all you have to do is ask one of your mates to just slow down enough for you to keep up and then follow the leader, when he goes to fast let him go and catch up on the straight bit's DON'T try to be something your not, only experience can teach you how to ride and good advice from those who know, my local police force does a weekend training course for most months of the year and it's only a few quid to get on the course, give your local force a call and see what they do in your area, a lot of the guy's on the course are there because they got caught speeding and it was that or a fine but some are there cos they want to survive. Ride safe mate.
