Thanks, yall, for all the inputs. The great thing about all the diversity
of opinion is that it stimulates thinking in directions that were previously ignored. While advice has been diverse, there have been some common themes: 1. Relax downward pressure on the nose. 2. Use more aileron. And although this is not specifically the issue I was addressing, 3. At rotation, smoothly transition to a wing-low attitude with the upwind wheel still on the runway and airplane axis aligned with the runway centerline, then when fully clear, transition to a wings-level crab. Now my analysis of 1 & 2. 1. I am not aware of consciously applying downward nose pressure, but I may have been doing it in my intent to not allow it to come up until I am ready to rotate. Forward pressure on the control wheel will cause an upward tailforce and take some of the weight off the mains. It also increases nosewheel authority when I really need rudder authority to counteract weathervaning without having the nosewheel tend to make the plane track to the downwind side. I can see that I probably need to lighten the nosewheel. A little back pressure on the control wheel will cause downward tailforce which adds to the weight on the mains, helping them prevent sideskipping. 2. I am sure that I have been way too timid with aileron. I know I have been using it in an arbitrary fashion without any real sense of control, or any understanding of what it really does in the crosswind ground roll. If the plane is trying to go to the right, I should roll in more upwind aileron. Too much will be indicated by tendency to sideskip to the left or the downwind wheel trying to lift. I know I should have mastered all this long ago, but I didnt, and now Im trying. Now I just need some good stiff crosswind to go learn to do all this....
