I thought about the Numbers the other day. It doesn't seem to get grabbed/surfed like it does when you paddle it, so I bet it would go! Keep me posted. I may just join you and we'll have a super mini-me extravaganza!
I do row it solo, but my frame has a bay up front with a 54 quart cooler. I just fill it with Pabst Blue Ribbon Liquid Ballast (PBRLB) and Ice. That's plenty of weight in my experience. It is kind of funny to have a 30 rack and a big cooler when it's just you, but if you roll with kayakers, they will love you.
I think the super duper hole punching ability does come from having a front passenger, however. How hard is that anyway? Just ask any old stranger, "do you want to have a lot of fun and not have to do anything?"
