Spinning Lures for Sierra Streams

Hi, I'm planning on a little trip to the Sierras in late August. I haven't
fished much lately, and I would like to take up fly fishing. Considering the
investment in fly gear and the time learning the craft, I'm thinking of
taking a small spinning outfit to fish the streams for trout.

When I was a kid, we'd go to the Sierras and stream fish with 4# test,a
split shot or two,#18 treble hooks and salmon eggs. We did pretty well.

Bait fishing doesn't do it for me. I'd like some recommendations on small
spinning lures to use in the streams and maybe a river or lake or two. I
know some streams are barbless hooks and c&r only, so I need to keep that in
mind as well.

Thanks for your help, mj
