I tend to prefer as sharp and thin an edge as possible for a given blade thickness, and a full flat or full convex grind will have a narrower angle and thus a sharper edge. But a saber grind will be stronger, leaving more blade at full spine thickness. I find the full flat grind of the DFLE cuts better and results in a lighter blade than the DF CG, so natually I ordered the SOD LE. It all depends on ones personal priorities.
