It is nice to have options though, but when you have multiples in various size ranges I think it is seriously overkill.
That's where my "desire to accumulate" collides with my "desire to be a sensible user".
If anything else "cool" comes along I will have to move a "safe queen" to pay for it. I'm really trying to become a "pure user", but as this is my hobby I know I'll always have safe queens and duplicates.
If the Busse family would adopt the Model T Ford marketing plan: you can have any color you want as long as its black - then I wouldn't have any safe queen duplicates, LOL!
