Everyone is going to tell you to get the 911, because its been a LONG time since the Yard released a "big chopper".
Your 6.5" Reg's blade is too thick for a lot of tasks. I have a standard Mil Reg, and while I love the knife...its not a good general use blade.
If money were an issue - I'd sell your 6.5" Reg and buy a 711 for GP use and 911 for batoning, etc.
