Giving more thought to your query Bob.....
The Mudmaster is the largest G in my collection. It has plenty of bulk/chunk to it!
I actually bought one rather early on, but sold it as I considered it too large. It didn’t wear too big on the wrist, but was a pain when taking a jumper, or even a jacket, on or off.
A fellow TZer (and G-Shock fan) kept telling me to reconsider, until I gave in, and purchased another. A slightly different colour version. It obviously remains awkward to dress around, but other than that I am really happy to welcome it back into my collection (various pictures on here!)
The Mudmaster, for me, wears significantly larger than the Rangeman, and despite owning both, I prefer the Mudmaster
