I replied to Fisher 4 Life's post below, but it's so far down the string, I figured no one would see it. So here's my Castaic report, which I'll happily share:

We were the fifth boat out on Castaic yesterday. Third cast we boated a 4# on a popper and a 2# on a buzz bait a few minutes later. That was it for the topwater action but the rest of the day was awesome. Hit a couple of the coves on the ski arm throwing poppers, Senkos and the bait of the day: 5" oxblood w/ red flake Roboworm, Texas-rigged with brass n' glass and drenched in Kickin' Bass attractant. I stuck to that bait all day and boated 10 including three over 4#. I also had two break off. My buddies threw the other baits plus crankbaits and jigs and only got 3 each. By the time they wised up and switched to the Roboworm the bite was off, although I caught my three biggest fish back to back to back between 2PM and 2:15PM. Most amazingly, I caught them off a sand beach with no cover and really churned-up muddy water. I was gonna skip that spot all together but my pal said to throw in there b/c the brass n' glass is good in dirty water and man -- was he right. Practically an instant hook-up.

I went online and ordered more of the Roboworms because they're pretty trashed after one or two fish. Good luck all.
