I certainly agree that the Frantz TP is a bit too small for the tight fit into the canister I personally prefer - and the outer wrap of the blue paper shop towels seems to be working well. I take 2 sections of those shop towels, still in one connected piece, and then cut them in half length-wise - making one relatively narrow strip. I then measure off the width of the TP roll, and carefully fold the extra width of material down over the larger portion. This makes about a 3/4 inch double thickness on one side of the strip.
THEN, I carefully wrap that around the new TP roll - this creates a slightly larger diameter at what I will install as the top of the fresh cartridge. My goal in doing this, besides getting an overall tighter fit, is to slightly increase the top diameter of the roll to seal better and prevent oil flow down the outside of the cartridge between it and the canister wall.
Been doing this the last couple of changes, and the condition of the old cartridges when removed is very nice and smooth, no distortion, and looks like the added outer wraps are getting the job done. I had just bought about 8 new rolls of the Frantz stuff to experiment with, and compare with the Scott - and then a member here offered me some rolls he no longer needed at an attractive price - so I have a pretty good supply to work thru! :-laf
