Your resolution at mileage that low will make it difficult to see a change. Make sure you check for sticking brakes.


Is there no way to change the angle slightly without a total rebuild? I noticed that a few degrees can make a big difference. Even if your tufts are flat you can be getting a lot of lift induced drag. Your tufts will be flat but dance more if you are close to the edge of separation. It's a hunch I have (an educated one) that induced drag spikes at that point. I have not found the paper that confirms this but from flying aircraft the butt o meter is pretty sure.
