I bought one for a little brookie rod right when hey came out. I bought the smallest one.
I fished it for a week in the Smoky and didn't have any problems with it.
They are light and pretty well built. The spool is narrow, so it won't take a lot of backing on it.

They come set up for left hand retrieve, but can be switched to right hand retrieve. *

It has a drag system that can be changed to four different positions.
There is a small block that pushes against a spring. The little post that the block sits on is mounted of center.
By rotating the block on the post, it will put a different amount of pressure on the spring.
The position that puts the thinnest part of the block against the spring will have the least amount of drag.
The position that puts the thickest part of the block against the spring will have the most amount of drag.

* Some of the first models have a problem when converted to RHR.
The drag wouldn't work as designed when set up for RHR.
The problem has since been fixed. If you have one of the old ones, Orvis will replace it.

I hope this helps.
