Canadian Wonder

Does anyone else grow Canadian Wonder. I opened a packet of Kings seeds (the bundle at the top of the picture) and thought they don't look right (quite small and different shades of red/brown) so I checked against my own saved seeds (bottom bundle) and as I grow these for the beans I'll be sowing mine and chucking the kings.

I have done in the past and think they were quite varied, both the original beans for sowing and the harvest, although I put that down to them not all being equally mature when picked.
