Paired Programming vs. Getting Input from a Co-Worker

So now that we have some experience in Ping Pong Pairing (PPP from now on), albeit limited, I find that while I'm working through some problem solving I'm also wishing I had another programmer to work along side. It's not good enough to get some co-workers opinion on the matter anymore, even though that's better than programming in a silo. When you are working together on the same code-base, you are both invested fully in the solution. You don't get half-thought-out, non-real-world psudo-solutions (man-I'm-using-a-lot-of-dashes). While doing PPP you are forced to understand the domain context and think through the code together. You are forced to think through the code and come up with a concrete solution together and I think this is a huge advantage verses the advantages or sometimes disadvantages to getting a co-workers opinion about your work.
