Yeah… that’s fun to do.
The C172 works great with the 530 mod; I cannot remember having a single CTD with the Mooney either.
I fly into KSEE and KSAN quite a bit, and into KSNA as well… right on the border of Class B airspace. KCRQ is another right on the border of Class B airspace. Traffic in that part of the world is pretty intense. I usually vector out to the VOR on Santa Catalina to keep west of the LAX Class B, and fly V27 to the Ventura VOR.
It’s a fun region to fly, and the weather is usually pretty good once you get above the marine layer in the summer.
