I will bring a variety of speeds and remember that it is possible to push and pull process film. Important note to self there I haven't done that much yet as I am currently getting the grip on DIY processing, darkroom and B/W film. Need to keep as few variables as possible in the beginning, but it's time for widening the usage of film and increasing my experience!
Thank you for all the constructive responses!
