Very similar to my first oktoberfest I did last year. 80:20 Vienna to Dark Munich. Single decoction with a 40 minute boil of 1/3rd mash. Lagered in March until September...great malty beer! If you aren't up for decoction, you can try a single infusion mash of 150-152, perhaps. With your grain bill, it might end up low on conversion so perhaps a little pilsner malt (for enzymes) may help or you could extend mash time.
