Why 6 handed?

[BigErf]

I have recently gotten into limit as I am primarily a NL player. It has come pretty easy so far at $2/$4. Am curious about 6 max. I know Ill probably have to drop a few levels starting out shorthanded.

In NL I can see the reason for playing shorthanded because aggression pays off but in limit you cant really "bully" and with limit I see the blinds as a huge factor...?

Anyone suggest what to look for or strategies on 6 max limit?
