Great question!
I think most people's decisions will be based mostly on where they are located and what they're comfortable with.
I carry mostly a small 4"-5" fixed blade and a saw...
I couln't say it better myself. :thumbup:

Though I'm know as a big blade kind of guy,

...I carry and use a 4" to 5" blade more then any other.
A knife is this size range handles most tasks short of chopping.
