seriously, just let the riders choose there group and then balancing out the rest, I was thinking may be let them ride with the riders they been riding with before and feel comfortable with, for example most of them with will be coming in as a group from a peripheral meet up, may be allow that same groups plus some others to mingle and then ride down? just announce the lead and sweep for each group? for example, Tpoppa and Inyaaz will be leads for the fast groups, and Hailwood volunteered to lead the med to slow group. Keep it like that and then ask the others to join up respectively, then move up or down group as needed? UP was recommending getting very experienced riders to play sweeper, like those who would be able to catch up with the lead from all the way back if needed for emergency. any more takers?
