HP C5180 printer, which photo paper to use?

I've been a big fan of Red River over the years, and I'm tempted
again.
(I've been using the 68lb Ultra Pro Gloss)

I do remember threads in the past saying that Office Depot made an
excellent photo paper.

I'll probably get 100 4x6 and 100 8.5x11.

I can get those two boxes of RR 68lb UPG for a total of $40 shipped,
not bad.

If anyone has any other suggestions, please let me know.

Thanks,

Scott
