Flyfishcolorado,
First, let me say Holy cow! Blueribbonflies are awfully proud of their flies! Someone on this forum touts blueflycafe.com where the flies are $0.65 apiece - check it out - I've used them twice this year and the flies seem to be of very good quality.
The crystal serendipity is something I've never used before. I usually fish a large 'stubby' nymph for caddis that works well. I bought a few years ago at the Orvis shop in Salida and can't remember it's name. It's also tied on a scud hook, size 16 is typical, olive (or tan) hares mask dubbing (hairy) with a turkey wing tied in at the tail and brought completely over the top of the body. Gold wire is used for the ribbing and there is a tungsten bead head. There is no tail. Pluck out a few of the hares guard hairs to make it look buggy. It looks something like this except I don't use the peacock herl or the hackle.

I also use a breadcrust tied wet. I've been experimenting with Fox's Poopah with limited success (can't recommend that pattern yet) and then always, always have copper johns tied on scud hooks - I'm becoming fond of tying them with two wires to emphasize the ribbing (i.e. one black and one olive wire).
Bitafurnfeathers recommendation for the LaFontaine Sparkle Pupa is right on - that's a known producer.
