Leaders with least memory? (Also, wallet suggestion?)

Just lost my leader wallet, and all of my leaders. Before I go out
and by a whole new set, figured I'd get your collective opinions on
your favorite mono-tapered leaders, and leader wallets. But also, let
me describe my experience, and complaints:

I generally use Orvis Super Strong Nylon leaders (usually 9ft, 4x -
6x), and very occasionally their flourocarbon. I love the lines for
their strength. I rarely break off a fish with this stuff. But, one
thing I really hated about this last batch was the memory. Every time
I'd get out a new leader I'd have to use my leader straightener 2-3
times, and even then it still had some curls. I tried out a different
brand today (I believe it was Dai Riki?), and it definitely had less
of a memory issue.

So - what're your favorite leaders, with little memory issues? Have
any of the magazines ever done head-to-head comparisons for this kind
of thing?

Then, for a leader wallet, I also used Orvis'. What I didn't like
about that, was that every time I'd get it wet (which was pretty
frequently), the fabric would take a while to dry. I'd prefer
something that didn't hold water at all, I think. Some kind of vinyl,
perhaps? Thoughts?

Thanks guys...
