Thank you Bruce!
One amplifying question: Where does the Mudder handle fall?
It looks as though it is bigger then the Basic but smaller then the Yardkeeper / Dumpster Mutt LE handle.
If so would the list, from LARGEST to SMALLEST, be the following:
1. Regulator
2. Dogfather / SOD / Scrapper 6
3. Yardkeeper / Dumpster Mutt LE
4. Mudder
5. Busse Basic
