Here is a selection of the lines that i use with my switch rod. On the rod is my Forty plus clear Intermediate fly line, i also have a Forty plus floating , a Di3 ( Brown ), a Di5 ( Grey not in picture ) , a WF 7 floating and a Floating line with a 12' super fast sink tip ( 8" per second ). Having these lines covers all aspects of fishing for the Monster Brown Trout, sometimes the trout are on the bottom in deep pools so you have to search them out with fast sinking lines that will get the flies down fast. If they are feeding higher up in the water column then the floating and intermediate lines will cover that, you are only going to get one shot at these trout so you have to make it count. Putting on a strong salmon tapered leader will help in the turn over of the heavy flies but the most important thing is to have a very strong braided loop ( Roman Moser micro-loops ) on your fly line. Make sure to cover the braided loop with two coats of either Storm sure or Aqua sure glue to add strenght to the loop, the glue also stops the fly line cracking just above the joining. Don't use super glue as it will crack the fly line at the joining and you could lose your dream fish.
