Love the DMDC wish the S5 would have been FFG. I am just not a saber kinda guy. The 1311 is the only saber ground blade I have. I keep buying them and selling them. Hope the MM is different.

Never liked the RMD but I love the thiner RMDux (or however it's spelled).

Personally I would say the TT Reg is a do it all knife. The 411 is nice and so is the s5 but both need a FFG. Never had an S6 but it seems like a fine blade.
