+1 on the Diskeeper Ultimate Audiophile inner sleeve.
I have MArecordings inner sleeves, Mofi, Blake, Clearbags, Bags unlimited and out of all of them I like the Diskeeper Ultimate Audiophile inner sleeve.
The Ultimate Audiophile inner sleeve is the only one that slides right off of the LP all on it's own when holding the LP by it's edge.
The MArecordings inner sleeves are pretty awesome, made out of a fine mesh that can breath, but to me, they are to delicate, fit to tightly, and to expensive for my
modest collection. I would use MArecordings inner's only on my finest LP's if I could afford them.
For everyday use, Diskeeper Ultimate Audiophile inner.
