Two very different problems here
With the OPer at about 180-200 pounds and the wife at 120, these are two quite different problems to solve in terms of picking a boat.
This wouldn't matter if the OPer hadn't said that rolling and more river work were in their plans. While it is nice, no one needs a well-matched boat for just puddling around a small pond. But with the plans stated here, the match of the boat to the paddler will matter. It is discouraging to try and learn skills when the boat is too oversized - seen that happen.
I suspect that there are a number of boats that would work fine for the person who posted this - though I am rather fond of the idea of going for the Tsunamis. New paddlers tend to think that running class 3 is a piece of cake and underestimate the challenge of class 2. A boat that'll get thru class 2 is plenty for most.
But it seems that many responses here are lumping the two paddlers together.
