IMO i'm all for drafting it keeps things interesting and you have to think ahead about what everyone else around you is gonna do. Like, when you do go and try and break away?
The Sup 11 cities race in Holland was an excellent example of drafting and tactics and it taught me alot.
Here is a pic of the lead pack in hollands 11 city tour.
I think the only rule that you can possibly bring in is the same class drafting, eg. a 12'6 can only draft a 12'6 and shouldn't draft a 14ft etc.
I've heard some talk about gender drafting aswell eg, a female can't wash ride a male. I'm not sure if this would work cos in my eyes if a female can hang onto a good male paddlers wash (Which isn't easy) they derserve to be up there, but that's my opinion.
