Good point. Perhaps what I wish I had was a smaller middle? (HAHA, yes, that's why I ride in the first place

)
The difference between the small and middle on the front is a big jump.
Possibly that 28-45-50 chainring setup that was popular in Waterloo for a couple years?
Always disliked it myself, but not to the point of actually doing anything about it.
Should be able to swap in a different crank for a couple of bucks... find a used triple with a square taper and it might be cheaper than buying new rings.
