What type of filters do you use, screw in or slot in? I've always used screw in, but I'm thinking about switching to slot in so I don't have to deal with step down rings, vignetting, having the same filters that are different sizes, etc.
Got a tip for us?

I don't think you can pick just one or the other. For grad ND filters, you almost certainly have to get the kind you're calling "slot" - Cokin "P", in other words. But for polarizers or plain old ND filters, the screw in type are much easier to use.
I voted slot because I don't usually use UV filters. I have a Cokin P holder with adapters to fit 67 and 77mm so it works with most of my lenses. You can get polarizes, grad and straight neutral density and about anything else you can think of in "P" size filters.
I standardized on one set of 77mm filters accompanied by a couple step-up rings, learning my lesson rather late after first buying a polarizer in 67mm thread, then one in 72mm thread, and finally one in 77mm thread.
The only filter I've had trouble with, in terms of vignetting, is the Singh-Ray Vari-ND at some rather wide angles. But part of that may be that I have a habit of framing my shots a bit wider than I think I'll really want, just to play it safe (more in terms of the final composition rather than a worry about vignetting). Also, I don't generally use UV "protective" filters - so if I'm using a filter, there's only one there at a time. I sometimes wonder if people that run into vignetting issues aren't pulling that "protective" filter off their lens before mounting their polarizer (or what have you).
