Does anyone use the Oxford page protectors? Are they any good?

I've always used the Avery standard-weight ones, but I checked 4 stores last night, and none had them. I could only find the economy and heavy weight. I bought the enconomy weight, but I don't feel comfortable using them.

So the only pack I could find that seemed to be somewhat OK were the Oxford's. I've never used them before, and just wanted to get some feedback on them.

Thanks! {thumb2}
