ok ok. last weekend i went there with bunch of non diving friends on a way to san diego (i'll tell about la jolla later).
We took catalina express from long beach @ 10am, back on 3.45 pm, so really only enough to do one nice dive.
I had my drysuit, w/BP, etc. stopped by scuba luv.
Rented myself a steel 95 faber, and snorkle gear for the rest of a crew.
(note fills there are somewhat short ~ 2300psi

Thats when i noted 3 sets of LP80 doubles in the corner. I was told that they filled with air, but they bank NX32 so wont be a big deal to give them heads up and do proper fill. Cost same as 2 tanks rental. They do not have plates or wings

so bring your own.
I had extra 13cf bottle with me so instead of getting insta-buddy i went solo, after talking to a DIR divemaster and getting directions @ casino point.
simple entry, warm(er) water. only 100g undies in my drysuit.
Bottom drops fast to about 50ft nice kelp (different from monterey), many fishes.
about 30ft+ viz., sunny no need for my light.
bunch of pipes and chains and other "home made reef" material makes a nice lively habitat.
over all very nice and i would repeat it with some DIR folks and make it a dive specific trip.
rent NX32 doubles go bit deeper.
next time i will fly to san diego,
bring everything but weights and tanks.
catch ferry from dana point to catalina., stay in san diego and do wreck alley too.
