We've only got a couple guys in the 3's who race together on a regular basis and we run things kind of along the lines Rubiksoval's post. We never enter a race with any real tactics and just kind of play it out for ourselves as it goes. Obviously intrinsic stuff like slowing the pack if one guy goes on a break or the occasional "hop on my wheel gesture" in the last few laps occurs but thats about it. It might be helpful if we worked together more but to be honest I've never really run into a cat 3 who is aggressive enough or willing to push me off their leadout train's wheel and no team is deep enough in the 3's to ride fast enough for long enough to stop people from moving up so I surf around and pick my spots and try to grab some points here and there. The 1's and 2's on the squad are certainly much more organized and I think its more important at that level.
