Stealth opener plugging prevention?

Hi there, wondering if anyone has ever had a fix for the banding tip on a stealth open. I use a 3.5 inch paired row 9 inch spacing on a flexi. I know the obvious answer is get a new opener. Trust me Id love to but with all the money I;m sinking into rebuilding the manifolds and meter boxes I kinda wanna avoid buying 10 grand worth of new openers. Next year. I never have issues with the seed runs plugging and if they do only one plugs and at least seed is still coming out of the other row. Anyhow, I;ve read some snippets about using shims/spacers/washers on the top bolt. I've also changed the banding tip to a Gen Manufacturing tip. Its a gumbo with a much larger heal and it did help improve somewhat. For Flexicoil and GEN 300 openers (GEN 49-1?, GEN 74-2?, GEN 59-3? point) | Wearpoints | Wearpoints

My soil has clay. Its heavy, Eastern Sask area. Appreciate any input. Thanks
