I'm going to be shooting both large format and digital, so I'd really like to invest my money in one meter instead of two separate ones. I'll be doing indoor portraits with two monolight strobes, so I'd like to know if large format specifically requires a spot meter for portrait work or if I can use an incident meter. I'll be honest, I am a beginner so I don't know too much about light meters in general, but from what I've read online incident meters are better for portraits because they measure the light falling onto the subject, and that sounds about what I need. I was considering a Sekonic l-308, but that doesn't have spot metering and if that's an important feature for large format then I better go with something else.
