Rod Weight Opinions

[Deer_Hunter]

Getting back into fly fishing after a long hiatus

Found a good deal on a Sage One, however it is only offered in 4 weight on sale.

Soliciting opinions on the ideal weight for southern Alberta - would mainly be fishing within K Country, Mountain Parks and on the Bow.

Guess I am looking for a good "all around" weight.

Realistically I don't see a lot of BC fishing in my future but would be nice to have a rod which kept my options open.
