Record Sleeves - Which ones and where?


I'm looking to replace all of my record sleeves with better ones. I've seen polyethylene, polypropylene, and rice paper lined. What's the difference? I'm looking for the best place to buy them too. Is it worth getting outer sleeves too? Please advise. Thanks!

Sleeve Town is sending me a sample of their best inner and out sleeves for free. I'll compare them to what I got a Music Direct and post about it when they arrive.
I finally received the free sample sleeves from Sleeve Town. The poly lined paper sleeves are identical to the ones I got at Music Direct (Nitty Gritty). The outer sleeves were the same quality as the ones from Music Direct, but were completely (and I mean 100%) clear. The Music Direct outer sleeves are pretty clear, but still have a haze to them. I like the Sleeve Town outer sleeves better, but since I already bought 300 from Music Direct, I'll probably stick with those to keep things looking the same.
I just noticed that Sleeve Town has the outer sleeves on sale right now (5.0 version). Get em' now guys, it's a good deal.
Hmm, Spenceroo, May I ask you this?
Where the Peel Strip is on the MusicDirect Outer Sleeves, does this have what appears to be some black ink Japanese writing? Mine does, and these that I have are prefectly crystal clear, like looking through a Pane of Glass.

I've once seen another Sleeve in person that MusicDirect once carried, that had a different "red ink" writing. Very similar, but there were some personal dislikeable differences, and didn't buy these particular Sleeves. Maybe somewhere along the line, materials used have changed?

Hi Mark,
The ones I got from Music Direct don't have any writing on them at all. They don't have a re-sealable flap. Mine are open on the end, and are just a tad bit cloudy. The Sleeve Town sleeves are crystal clear. My Music Direct sleeves were the only ones they had in 6 mil.
