Re: A switch outfit for trout?
You would be surprised how much backbone that the Echo 6 weight switch has in terms of handling fish and throwing hardware. One of my friends uses his 6 weight with the 390 grain Airflo Skagit Compact line with 10 feet of T-8 or 7.5 feet of T-11. When he wants to indicator fish, he puts on a 10 foot Rio floating MOW tip. Last week he landed three Steelhead ranging 23 to 26 inches on Intruderish style flies.
You may want to lean towards a 7 weight if you want to sling T-11 and T-14.
If you want to throw Spey style casts with larger flies, I would not recommend the Rio Switch line. It is a better nymphing line than a Spey line due to the longer belly. A shorter Skagit style head will throw large flies easier which means it should be easier on you.
As for reel sizes, a #4 Ross Momentum LT or CLA can hold shorter Skagit heads up to 425 grains with ample backing. If you desire more capacity, you can use a super braid line as backing. Keep in mind that you can also gain capacity by cutting 10 to 20 feet of running line.
