All advanced riding is worth doing, bike safe / blue riband/ i.a.m etc I did the Blue riband instructor course some years back when I instructed, we did a very intense 4 day police course down south with the coppers, did some great riding, also over speed limit stuff which was great as we were riding with the bill and them radioing to other units that they are having a bit of fun so ignore 2 sportsbike riders giving it rice.. I still practice and help out mates now and then, we generally helped out either newish riders(6-12 months exp) or born again or mature riders that wanted to hone in on skills. You learn everyday so any type of advanced skill is worth it.
