Just finished up this mod to my DX9.

I tried just replacing the grease with TriFlow synthetic grease = no difference
I tried sanding the plastic cam with 600 grit sand paper = better, but enough
I tried polishing the inside of the metal finger to a mirror finish = better yet, not enough...

Finally, I tried this mod. MUCH improved and no difference in tension from top to bottom.

Thanks to all who figured this out!
