RN,
Interesting question.

I'm passing between them now...

Overall the 411 fills the hand better, but the index finger area feels cramped. I always find myself choking up on the 411, and sticking my finger in the generous choil area.

The LM feels like a more svelte and precise instrument. The index finger area is more comfortable.

Conclusively:

The 411 feels like better with a "closed grip" (stabbing fist with a knife stuck in it).

The LM feels better with a "finesse grip" (more like when holding a writing instrument with the index finger pad positioned behind the choil/talon hole).

I'm not sure this makes sense?
