I have a couple one piece rods, a seven foot jigging rod which works quite well. My other is a cranking rod. Both have a nice feature of retracting into the handle so you don't have the full length when storing.

I've not noticed a big enough difference to compel me to switch over, but they do feel firmer in use.
