I was thinking more about this.
I guess it all depends on what your goal is. Will you be a serious competitor (we're not necessarily talking Nationals, but more like are you going to take it very seriously)? Or are you just in it for the fun and could careless if your dog blows things?
I know with Koji, I was just having fun with him. Agility was something to burn off energy and nothing more. Going to a trial was just something to do. When I entered, I only entered those games I was confident in (weavers, tunnelers, jumpers) and stayed away from everything that could potentially scare him away from agility forever (especially cuz he was/is such a scaredy cat). I knew I wasn't going to take agility seriously, wasn't going to care what he did or didn't do. Granted, I was WAY WRONG with my assumption (no one told me agility is like crack

).
I started Koji in Standard/Regular WAY too early. I should've focused more on the DW and his contacts. Remember when he was going so slow over the DW and visibly scared? Why did I do that to him? Ugh! But, honestly, I think I'd still take a dog out for games I know they can do and that won't give them bad habits. I just won't push it like I did with Koji. So, when I get a second agility dog, I'll just continue games until they are confident and completing obstacles correctly. Granted, I think it's easier to wait with a second dog, especially if you're still running a first. lol.
So, it sounds like you'd rather wait. Which is good. Just remember, if you do want to trial, but don't want to push it, find games you KNOW your dog will succeed at and stick to those until you're confident in other games.
