i think that the city centre / sports halls would be a good idea as they would be easy to get to and find then the middle of a forest in no where.
i like the idea to of more uci world style sections but these would possable cost more to set up and put on would the riders be willing to pay that little bit more on entry to the event.
we will try the tape idea at a full comps, but this sometimes limits the options on getting through the gates (without swinging the bike) and i know from the pst that we've had rides moan that things are impossible so we stopped using to much tape as it was turning riders away
