Hi all, my recently aquired 415c with c75 has eissman la4 mags of unknown age as the logs were incomplete. My A&P suggests that if they are determined to need replacing that I use slick mags as although the Eissmans can be bought rebuilt from skyport at a lesser price, theircparts are 60 yrs old even if new. whereas the slicks are more modern, albiet twice as expensive. Your thoughts? Thanks
