i did the shredded PTB for a while, but i got bummed cause u cant rinse and re-use, I started using half a TB (like stated in the post) and rolling it LOOSLY so it fits snug in the cart, having it loose makes for good absorbtion and drag, and it will rap around the atty nicely (cut it flush with the cart, not recest) honestly doesnt work as good as shredded, but def. better than the original, no leakage either, and re-usable!
I thought it would be a pain to clean too but after working with the Revolution brand PTB, Lipton PTB shredded or not is really easy to work with. Im able to take them out, clean them and replace pretty easily like dokie says. Folding them is easy too.
