The 11 series that I have are as follows. 311: 3.5" x .187"t 8" O.A.L. 511: 5.5" x .195"t 10" O.A.L. 711: 7.5" x .250"t 13" O.A.L. 911: 9.5" x .260"t 14.5" O.A.L.
So maybe the 1311 will be 13.5" blade, 18.5 O.A.L. I'm thinking it will have to be .250" thick in order to fit the handles in stock.
This sounds like pretty good thinking to me. You just forgot one thing though...... INFI <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
Seriously though, I hope it's INFI...... but I wouldn't be surprised if this one was SR-101 like the rest of the bunch. Either way it will be a beast, INFI would just make it more of a beast.
I'm glad we can call it the 1311 now instead of the FDM.... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
