Hey there,
All the tension rods on this kit appear to be the same. I have included a closeup of a lug and t-rod for the 12" and a pic of the floor tom's parts on the table. Magnets do not stick. There is a small flake on the floor tom rim and it reveals a brassy color. Magnets do not stick to any rims on this kit.
I am almost done with the floor tom. I have also posted a pic.
Found a few pieces of paper in a couple of the bass drum lugs. Other than that, no felt anywhere
