(Assuming you don't have your own established in-group that tends to be in every single RP together.) I'd certainly say it's the one section that will waste the least amount of your time.

The 1X1's will start faster and last longer on average. (Regardless of their complexity.) The OOC (out-of-character) communication is easier for obvious reasons. And its conclusion will usually be more obvious and transparent too.  

Plus, the 1x1’s usually let you know the desired quality and quantity ahead of time. (And the best ones provide writing examples on top of it.) So you don't have to worry about the fake authority of GM's and Co-Gm's. (That will often only use their titles to dismiss outsiders from their preferred group.)

But I've also seen people create small group RP’s. (For three or four players.) So I’m sure you’d be able to find something that works out. (Point being, don’t let me stop you from trying. But I’d certainly suggest starting your own and being proactive, if you’re looking to start a group and not have it take over a week just to get started.)
