i've always used a traditional spinning set-up and want to try and fly/bubble set-up this summer. i mostly fish high sierra lakes.

how do you set this up? what flies should i bring? other advice?

I use an A-Just-a Bubble

I just put any yummy looking fly on my 4lb mono. Bubble goes on first, and you twist the middle rubber part to lock in in place. I usually vary the depth so that it is at the same level as the fish.

You can also fill it with water to add weight and cast further.

There are some great thread on here (search: "spinning bubble fly fishing") with pictures of hikers' rigs and details. Also, as you get to Lone Pine, drop into the Sporting Goods store there with the big fish outside and spend a few bucks on the most-recommended flies...and get all the local beta and insight for free from the great old guys behind the counter!

For flies, I suggest a selection of small flies, such as the red-ant, mosquitos with red in them and maybe a couple of teeny ones with little pieces of red foam (no-sink) in them. These are used with the bobbers for the "bobber and fly" setup, particularly during "the rising" at sun-up and dusk. I carry mine in a take-out taco sauce container and many local fly-sellers will give these out, too.

And then do a few more searches! :)

To avoid tangles part of the time, after casting, grab your line before it reachs its furthest, that supposedly causes the bubble to stop and maybe let the fly clear it. Get half a dozen different flies and maybe a couple of the regular ones. I had one red ant fly I'd been packing for years, never used it and at Rae Lakes there was a hatch on, I killed the Brookies with it.
