I've been there a couple times and never surfed anything under chest high. Your all around board is probably your best bet unless you see some purple blobs on the surf forecast....I'd let that dictate if you should take another. You may get charged more for taking 2 boards though?
Ya.... outers at Popoyo can get seriously ridiculous! I often see guys with helmets and guns goin out there. It can get pretty big! For most going to Nicaragua on a surf trip aren't going to surf the outer reef. People have died out there and many have been seriously mangled. The nearest hospital isn't so near either.
So besides outer reef just bring your regular board. I usually bring a 6' - 6'1" basic thruster and my 5'7" fish. Actually rode the fish most of the time. Got some killer picts of me on the fish in a stand up barrel! I have never ever been to Nicaragua and had a shortage of waves. On one trip we had some guys who weren't quite as experienced and there were a few days it was just too big!
If you are not an experienced surfer I would recommend going with a guide and letting them know you need a less aggressive wave. It seems there's a lot more reef and rocks and funky currents then if you go on a trip to Costa.

This might be really obvious but check the surf report before you go and bring whatever you need to cover the expected waves just like anyplace else.
My experience has been that a standard shortboard covers just about everything except if it gets huge and you want to do toe ins on the outer reefs. I don't even own the sort of boards that would have been required to surf the biggest days last time I was there but there were some nooks and crannies where my regular shortboard worked just fine even on the biggest days.
