Definitely don’t mention brookies..
the difference between East and West.. here in the West little brookies are frankly a bit of pest, overpopulating and crowding out the natives..
back East I used to seek out brookies, at least as much because the streams where they lived would be remote and beautiful, as for the fish themselves. Out here I use paveglass' line all the time when spotted with a rod in the backcountry ;-)
The best I can do in glass is 4-piece, a FF756-4 and a 8' 4wt I built from a blank. These will both go in the pack with a little care.
In graphite, a Redington Trout 5wt 9' in six pieces, and Cabelas Stowaway 3wt 8.5' in six pieces, are very convenient and much better rods than expected, tend to pack these when flying as they will fit anywhere.
